I did submit this to the how to article section, however because of several ppl asking me for the how to directly i have decided to put it up as a thread and when ever it gets reviewed as a "how to" it gets reviewed.
"Usual disclamer"
GT CAI How To (this also works for the ST celica as well)
Tools and parts:
Metric socket/ratchet set
Screw driver
Hack saw
Dremel
¾ inch hole saw
Permanent marker
90-93 Honda accord CAI system (2 piece 2¾ in. pipe)
The Concept Design:
Step 1: Prep
Take out the stock air-box. This is done by disconnecting it from the throttle body, Unbolting the air box as well as taking out the resignation from the front fender (note; this is where the air filter will go). When taking out the air-box you will have to disconnect a breather tube as well as a temperature sensor. The temp. sensor can simply be puledl/wiggled free from the rubber flange that holds it on. After pulling the temp sensor out remove and save the rubber flange.
Step 2: More prep
Next thing on the list is to take out or rather detach the fuse box from the car. To do this there are three bolts. Two are under the cover, one is in the back and one is on the side. The third bolt holding the fuse box down is in the front and at the bottom. At this point take note of the bottom of the fuse box as it will be attacked by the friendly dremel.
Step 3: Modify “S” pipe
Now with the engine bay free of the stock air-box its time take a look at how the piping from a 90-93 accord CAI system will be used to route a CAI system for our GT’s. There are two pieces of pipe in the accords CAI package. The first piece has an “S” type shape as well as a small pipe for a breather tube. The second piece is shaped more like an “L” and this is the pipe that will be routed through the fender where the filter element will be mounted.
Test mount the S pipe to the throttle body using the supplied couplers. Next take the L pipe and stick the short end down and into the hole that’s in the fender. If you care about scraping the finish make sure you’re careful when navigating the pipe around the fuse box and into the hole as well as placing cloth anywhere needed.
With both pipe soft mounted you will see that the second bend from the throttle body routes the pipe on a tighter angled vector then is needed to mount up to the L pipe properly. Luckily the L pipes length is just perfect and it reaches all the way out to the second bend on the S pipe and ends just exactly where the cut in the second bend needs to be made. Use the permanent marker to mark off where the cut on the second bend of the S pipe needs to be made and take Mr. Hacksaw to it. Clean off the edge as well as any stray derby and or saw dust.
Step 4: Modify “L” pipe
At this point the only piece of pipe that should be cut is the second bend on the S pipe. The L pipe should be untouched, but not for long. After cutting the second bend on the S pipe a coupler should be able to link the S pipe to the L pipe, which should be routed through the hole and down into the front fender area.
With the front left-hand splash guard off the filter element should be able to be mounted on to the shorter end of the L pipe that’s sticking through the hole. You might note that there is more pipe then needed sticking though the hole. Test mount the filter element to see how much of the pipe needs to be taken off. If the pipe is too far into the filter element it probably will lead to airflow restrictions but it will be louder because of this.
If your planing on fitting a bypass valve as i have done a section of pipe is going to have to cut to allow the fittment of the bpv. It is best to make the cut on the L pipe rather then the s pipe.
Step 5: Temperature sensor
With the S pipe soft mounted to the L pipe, now would be a good time to figure out where you want to drill the hole that will mount the temp sensor. Chose a place and make sure that the sensor will reach it. Then use a ¾ inch hole saw to make a hole in the pipe. The hole should be the same size as that on the air box which held the rubber flange for the temp sensor. Slip the flange onto the hole and test fit the temp sensor.
Step 6: Fuse box modification
Now with the pipes cut and mounted you should be able to try to mount the fuse box back in its original location. When doing this you should be able to see what and how much of the fuse box needs to be taken off.
The bottom of the fuse box can be taken off, this exposes the plug. All that needs to be shaved off is some of the sides and bottom of the fuse box as well as some of the plug. This step is best done with a steady hand and a dremel with a “cut off” blade. A slow yet steady approach is a good idea.
If you don’t want to bust out the dremel then the fuse box can be left alone and either secured by zip ties or longer bolts can be used to hold the box in to place via stock mounting points.
Step 7: All done
Now that the pipes are cut, the hole for the temp sensor is made, and the fuse box is modified the pipes should be able to be mounted using the couplers and air filter that it came with. After getting everything back together start the car and enjoy the sound of cold air intake.
Here are a few other member's setups as well

Notes:
EBay has the cheapest 90-93 accord CAI systems, but make sure it is the two piece type like the one on Pro Car Parts.
Some 90-93 accord CAI piping have two breather tubes rather then just one. From my experience with Pro Car Parts and EBay, the chrome set has two where as the powder coated one only has one.
the use of a bypass valve. It is not needed to work properly however it is something you can ad on to protect against hydrolock. Keep in mind that inorder for hydro lock to take place almost the whole filter element needs to be submergered in to water. This would have to be avery deep puddle. I drove around with no bypass for a long while with no troble. I put it on when it started to rain heavily and because a shop i was checking out had one in stock.
WARNING Must use 2.5 inch pipe if not moding the hole below the fuse box. If you use 2.75" pipe the sides of the hole will rub a cut into the pipe.
If you use 2.75" cut the hole larger.

*picss doens;t work*
grrr cant figure out how to get all pix to work so they are in link form. If n e one whats to give it a shot ur welcomed to take a hack at it. Tag ur it.
Coomer these are the pix that i was guna send you. I know ur busy so take ur time no rush. I can still email them to you if its easier. I posted the how to up because there were several ppl asking me about it. Hope i havnt over stept any lines.
I placed youre photo;s on mine webspace:
What do you do with the breather hose that comes with the intake? Not sure whether to plug it in to the throttle body or valve cover or just to plug it up and not use it.
Thank you all, this is the first detailed instructions on the GT CAI. This is overdue for years. Thanks urbandork, im gonna go try it.
how is this 20-30 bucks? the bypass valve alone is 30-50, not to mention a real name brand filter is around 40-60
not to be rude or anything, but for people who follow pictures more to put the instruction under the pic..still would need a bypass right digndoug?
What is better, diameter 2 1/2" or 2 3/4"? Lots of the ebay kits are 2.5"
In responce.
First off the price of jsut the CAI should be around 20 to 30 bucks because that is aournd the lowest price you can find it on ebay including shipping. The filter is usually included with the CAI system when bought. The bypassvalve is an options that must be outsourced and thus the price is not included in the project build. This also holds ture if the builder wants to use a diffrent airfilter.
Second the hoses that are supplied with the kit because all of the stock hoses, just one at that, can be plugged right back on the CAI piping with out over stretching it. If a color theme is needed then go right ahead and do so.
Thirdly going back to the use of a bypass valve. It is not needed to work properly however it is something you can ad on to protect against hydrolock. Keep in mind that inorder for hydro lock to take place almost the whole filter element needs to be submergered in to water. This would have to be avery deep puddle. I drove around with no bypass for a long while with no troble. I put it on when it started to rain heavily and because a shop i was checking out had one in stock.
opps almost forgot. The pipe diamiter of my kit was 2 3/4 inch. I would not suggest any larger as then the whole that the pipe routes down into the fender by would need to be modified. This means that i would advise the builder to ask how large the pipe is before buying/biding on any items
As for what is better i was told that 2.5 is the best for the 2.2l.
Some one please make this into a "HOW TO." I really could have used this when I got my car. And I'm sure it'd help out all kinds of newbies.
Awesome bro here is mine, I made it out of Mandrel Bent Piping, and hand polished it it cost me around 80 to make.
-Brandon
okay so which version is better!!! and redline, where did you move the black box? can anyone help me modify my short ram injen to make it go cold air??
I'll be honest, I like Urban Dorks set up better than mine just because its cooler haha. But I have gotten alot of props from local tuners on my work.
Either way Urban our cars sound beastly and better than any civic. Woot
-Brandon
(and that little blue tube running off of my intake is my O2 sensor.)
http://www.lewfx.com/celica/DSCF0001.JPG
if you want a pic with the filter and heat shield off, let me know...i just took out the last part of the stock box, what a pain!
im sure all i need a certain piece to connect to the injen end and have the other end go through the hole...but what piece is recommended
how big is the pipe. looks like 2.25 or 2.5 inch. If you want to extend that for a cai system then ull probably want to use the same size pipe. Try to find a cai kit or pipe thats the same size and firgure out how to route it. By the looks of it you might want to cut the pipe you have and extend it so the last bend is farther down. Or you can see if another section of pipe with a bend similar to the L pipe in the how to can be modded to fit.
personally you might be better off selling the injen for a hi price and then use the money to get pipe off of ebay. This way you might even make money back lol.
there are many sizes being quoted of the pipe that gets connected to the TB
what is the actual diameter of the entry? on a 5sfe?
ive heard things from 2.25" to 2.75" (now thats half an inch gap!) anyone know?
if memory servs its 2.25
the injen is 2.5 inches
This really really needs to be put into the how-to section. Coomer?
lol i already fowarded it in the how to section. its pending aprovale. C man said he will get to it when he can. I feel him tho school, work, play, everthing else. days get short lol.
at least its on the board some where lol. Plus ppl can always bump it.
I just installed an Accord CAI into my celica yesterday, its working great. Car is much more responsive, it sounds like a monster. My car use to pull like a sissy on 3rd gear, now it rockets. I found that my OEM pipe was cracked, didnt notice before. You guys should check your intake pipes.
I would like to note that I got the 3" accord cai, which is too big. GET 2.5", stock is 2.5". 3" does not fit into the fender hole, had to increase the size of the hole. Had to remove the bottom of the fuse box. Fuse box does not fit into original position.
yes as its posted in the parts list the pipe should be 2.75 as anything larger will require making a larger hole as well as moving the fuse box. As it is, 2.75 bairly goes into the stock fender hole.
Also keep in mind that the CAI is going on a 2.2l. In reality theres no reason to go with n e thing over 2.5 inch. N e thing larger will see marginally smaller throtle responce. I went 2.75 because at the time it was the cheapest and i didnt find n e body with the kit in 2.5 inch form.
btw operative do you have any pix. you should post them in intrested to c what it looks like with 3in pipe.
bump for that guy
bout the 90 accord version as well, took about an hour to get everything in. bpv will come today.
aite guys, I've loaded a pic to my profile of the 3" CAI.
I lied, I was so excited to get my CAI, I just installed it. Its so freaken awesome!!! I haven't properly mounted the fusebox as I was afraid to take the dremel to it, but the instructions where very helpful.
BTW, the guys over at Pro Car Parts are very helpful and nice. I highly recommend them.
ill try to post pics of mine as well when i get my newer bpv
Not to bring back a thread from the dead, but I just finished doing this to my car and I have to say I like it. Very sexy growl from the intake I still need to installl the temperature sensor in the intake, I didn't have a hole cutter (and after having a dremel wheel shatter and embed into my nose I was done working for the day lol). Definitely worth it I think, kind of a pain to get the lower airbox out tho
~Brian
bump
Obviously this should work for the ST (7afe) as well... ? correct
depends on the placement of the intake manifold is realitive to the engine bay and whole in the fender.
on a 5sfe in a celica the bends and lengths are just right. I would think that if the placement of the intake manifold are to farther foward or behind then the 5sfe then i might have some troubles when dealing with the angle of the pipes and length.
Id say try it and at most lose 20 or so bucks on the pipes. At least ull have fun cutting stuff up and junk.
o also i dont know if the intake side of the manifold is the same size and thus you may need a smaller reducer.
I'll give it a shot after my car comes back from the mechanics.
urban give me a link of the right intake to buy
ebay...90-93 accord cai...2 piece
I bought a CAI for my car ST off ebay for like 30$, works great. I left out the bybass valve cause it took away the sound of the intake.
My new re-routed cai, works nicely
Hmm...so you sure as hell should have a bypass valve if you're gonna have it there...looks like danger for puddles...
i covered it back up with the plastic shield, just took a pic to show
I found a ton of bypass valves all diff sizes too not for $40-50 but $20 here they are there are lots of diff styles too. http://search.ebay.com/bypass-valve-intake_Parts-Accessories_W0QQsofocusZmppfQQsbrftogZ1QQfromZR10QQsojsZ1QQsacatZ6028QQmppfqyZbypassQ20valveQ20intakeQQsargnZ-1QQsaslcZ2QQsadisZ200QQfposZQ5AIPQ2FPostalQQftrtZ1QQftrvZ1QQfsopZ3QQfsooZ1
also what is the hose coming out of the valve cover into the throttle body do and why do some people have it going into their intake piping????
WARNING Must use 2.5 inch pipe if not moding the hole below the fuse box. If you use 2.75" pipe the sides of the hole will rub a cut into the pipe.
Pix of mine soon to come.
If you use 2.75" cut the hole larger.
Well I finally got my cold air intake done...well... almost... still need some bigger hose clamps and put everything back togther...
but here are a few quick pics of it...
Accord 90-93 kit
running under modified fuse box..
Thank you everyone for the help and special thanks to urbandork for the how to! :-D
easy?
not completely easy.. but it wasn't anything difficult... just time consuming...
1. get the inside fender cover off..
2. getting fuse box out..
3. widening hole under fuse box.
4. cutting 2 small parts off pipes with hacksaw..
took me about 4 hours total
right on man. im glad to c the how to did someone some good.
Nice pix man. Urs came out very nice.
only problem is the filter is pushing into the fender plastic so the tire rubs slightly when i make hard right turns... not sure if i'm just gonna leave it or add a little elbow to point the filter towards the front...
not sure... but i love how it sounds!!
Got bored so I decided to do this.
Works pretty well. I noticed a nice difference from my short ram.
Is that a 96 engine in your car Boss-Celica? I have a 94, and I've never noticed the differences before. I thought the set up was almost the same with all the 5sfe motors. My egr valve is different, and that vent hose coming out of the valve cover.
valve cover to TB and there was another from the back of then engine to the pipe. but seeing as they both suck before the butterfly valve it probably doesnt matter.
Its been discovered that this cai also works for st's heres the thread
http://www.6gc.net/forums/index.php?showtopic=34158
hey cool... i'm a part of the sticky.
Im just putting this out there....Saves you time and the hastle...ebay
Yay I put mine in today... there are some adjustments that need to be made but it is fine for now. I also had an idea. Where the filter comes out in the fender, what if a 90 degree was put in there to make the cone sit horizontally in the fender. Depending on the feedback, I am going to try it.
looks good chucks, hows it sound? i know youve had stock airbox for a while haha
good job. where's your battery?
oic. now get a bypass filter.... just in case.
where is a good place to get a by-pass filter?
ebizzle
I just noticed that the hole between the stock air box and the fender is different on my '99 GT than ya'lls is. Mine is farther back towards the suspension and a little easier to get to. I will post a pic when I can. Strange that they changed something so trivial in the later years. I can say that it would be easier to route piping wise but it would require cutting a larger diameter or using smaller than 2.5" piping (not a good idea IMO).
All in all I just decided to stay with my 3" short ram run to the hole and left the stock lower airbox and piping so it would get at least some cold air.
The reason why is I sucked water into my engine when the car was stock and it really sucked getting it out and then having to change the oil before driving the car again. How does a bypass valve prevent this? If it works 100% I may decide to CAI just for the f*ck of it since CAI vs. Short ram is a minimal difference at best anyway.
i'm pretty sure a bypass valve prevents hydrolock 99.99% of the time. its like a seperate mini air filter that works when your normal filter is submerged in water.
HOLD UP!!!
All i have to nuy is a Accord 90-93 CIA kit and bypass valve and i can make this happen wif above instructions...
What are some of the HP gains?
I take it this one will work with this mod?
if you get the accord cai, most the time the 2 pipes are different sizes so it would be difficult to use a bypass valve, get a one piece aem version, cut in the right location, add the bypass valve as a coupling.
aem is not cheap!!!
aem does not show one for a st204
its carb legal! and not cheapy piping
but i found an ijen
injens for our car are SRI.
excuse my dumbness what is SRI?
I could not find an AEM for our hotrod
10-4
IM NOT TOOO BRIGHT SOMETIMES!!
well alot of times
any idea if this works with the ST or possibly a 7AFE Corolla?
Just wondering what is that thing under the stock air tube. It hangs on the bottom of the tube.
does anyone know a reputable seller on eBay that sells the 2.5" piping 90-93 accord cold air intake? all the listings i see are 3" isnt that too big and what would the difference be between 3" piping and 2.5"? any performance difference?
it would bog down
after a while. i finally decided
hope i get 100 + HP
it helps to put a trd sticker on the piping.
cannot believe all this junk came from a tiny space.
anyways here is the semi-final view. Its not done, i dont care for the chrome, it will be repainted soon.
I did it a different way, this is completely reversible. I did not cut the fuse box, i made custom mounting brackets. PITA. Ill post pictures of the brackets later, as im heading for work.
But i like the looks, BTW is this supposed to sound like a vacuum cleaner.
yeah it does have a vacuum cleaner sound to it because it is not that restrictive. a cai and a sri sound the same. it's just the way it works. PFM i tell you. PFM.
With the brackets i used, i can even manipulate the tube wihtout taking the fuse box, plenty of space.
just my 0.02
here is my bracket system ... for the bottom
here is my bracket system ... for the rear and side.
and the fuse box mounted....
oh heres the vacuum cleaner....
my car has a cold with a deep raspy voice......
on the interstate!!!!

I removed my CAI in favor of an SRI. I like the sound of the SRI better.
http://www.diynetwork.com/diy/ab_engine/article/0,2021,DIY_13686_4888966,00.html
i highly suggest reading this article it is relatively easy and solves everyones problems (hydro-lock) and hot air from a SRI.
i know it sounds to good to be true but def read
What do i need to do to just mount the pod in the engine bat without a CAI.
Just want to get the filter in and i know there are more gains from having the CAI, and that will come later, but just need to know what is required just to do a basic install ?
hey is this the CAI that he used : http://cgi.ebay.com/ebaymotors/FALKEN-1991-Honda-Accord-DX-LX-EX-L4-Cold-Air-Intake_W0QQitemZ290389063227QQcmdZViewItemQQptZMotors_Car_Truck_Parts_Accessories?hash=item439c89763b or this one http://cgi.ebay.com/ebaymotors/1990-1991-1992-1993-HONDA-ACCORD-COLD-AIR-INTAKE-BLK-90_W0QQitemZ350309184144QQcmdZViewItemQQptZMotors_Car_Truck_Parts_Accessories?hash=item51900df290
BUMP!! Can someone find the cai on ebay for me just incase por favor
I'm a Jersey 6GC. With our weather, it probably doesn't make much sense to put in a CAI because I'm thinking if its closer to the bottom then, chances are rain water and all that are going to get sucked in. Any thoughts?
you can still do it, and it will work fine, just watch out for huge puddles when it's raining lol
bigger it is more air can flow through!
Thinking of doing this and have done quite a bit of research and have a few questions
1. I have noticed on a lot of other forums people have suggested using non metallic piping as the pipes will heat up due to the heat under the bonnet, which will negate the effect the cold air intake has. If the piping was to be wrapped in header wrap, would this effectively keep the piping cool or would this be a bad idea?
2. Is the stock resonator integral to the stock air system? If not could you disconnect it and close up the hole in the system to provide the sound and then just use a K&N drop in filter?
3. Has anyone used a pre-filter? Do they restrict air flow? and are they worth it?
4. The bypass valve will reduce hp gains and sound from the CAI. In the end, is it just for the bling look under the bonnet? Because from what i can gather the gains expected are 3hp at max and the bypass valve takes away 2-3hp.
Sorry to be a pain, my car is my baby atm and don't wanna hurt it =P
Thanks
Will this kit work?
http://www.ebay.ca/itm/1990-1993-Honda-Accord-L4-Cold-Air-Intake-All-Models-/140580579505?pt=Motors_Car_Truck_Parts_Accessories&hash=item20bb4168b1
Just out of curiosity, I saw this on ebay and wanted to know if anybody has used this CAI kit or knows about this?
http://www.ebay.com/itm/90-99-CELICA-1-6-1-6L-1-8-1-8L-2-2-2-2L-COLD-AIR-INTAKE-/290533100661?_trkparms=algo=LVI&itu=UCI&otn=3&po=LVI&ps=63&clkid=5132998992933921450&_trksid=p4506.m7&item=290533100661&vxp=mtr
Can anyone tell me what model of an SRI would fit our cars?
i was going to get the CAI and just cut it down but it seems a waste if i can one to fit straight in?
has anyone got any pictures of a homemade/modded SRI?
moving in favour towards the SRI with hood vents due to the flooding in my area lately.
Look on ebay, you can pick one up for about 30 bucks.
Depends what you want.
Injen makes a SRI, or you can just get a "no name" one and throw a good filter on it, its all the same.
Got mine from a seller called "chromeintakes"or something like that.
Just search 95-99 celica short ram intake or something of the sort, and you'll find something.
Thanks, what's your opinion on the chromeintakes setup?
It suck I have to pay triple just in postage!!!
Ohh yea didn't realize you were in Austrailia.
Try looking for something on ebay.uk, or something similar so you don't have to ship overseas.
I love the sound of mine, nice and loud.
For performance, it probably does the same minimal amount every SRI does. I can't really remember the change I noticed when I did put it on cause it was so long ago.
Thread REVIVE for my SAKE! XD
So I got the 2.5" Accord CAI 2pc set and I tried to install it but the throttle body is smaller than 2.5". Went around to local auto stores and they didn't have any 2.25" to 2.5" coupler. So I ordered one online and hopefully it'll fit.
