[Supersprynt]

k&n

[97GTinKC]

Amsoil Foam Air Filter......TS09 $28.10 (fits stock housing)

[doGGy]

None of them

Actually by filtration Element the best one is A'PEXi Super AIRFLOW filter, next would be K&N.

A'PEXi is dry filter - this means you dont have to wash it and oil it, but it will last for about 50K miles and then you have to trash it OR try to clean it, what i did

K&N is a wet type filter - this means you will have to wash it and oil it, that it was able to filtrate air at his best, but it will decrease airflow...

You deside..

K&N = TRD

[Supersprynt]

K&N is more cost economical...unless your goign to be doing good things with ur engine, get a good, not overly expensive filter (Apexi) like the K&N.

[Negative]

I personally think the ram air intakes are much better than the drop ins. I get a lot more performance out of mine despite what other people around here might say and have said.
That being said - I have a TRD drop in I might be persuaded to sell. It's used but infinetly cleanable and is a pretty red that you can barely see around the rim of the box.
Make me an offer.

Well first...we dont have ram air. IDK if ur talking about a cone filter or not but its not ram.

And I was torn between the K&N and Apexi, but the Apexi just was way to much money, but i've also seen many debates about how better the Apexi actually is over the K&N, so i just decided to get the K&N.

[Negative]

Enlighten me what is the difference between ram air and a cone filter?
As sold it was called a ram-air. Check out the picture on my profile if you have a question as to what I am talking about.

[S_C_M]

Ram air is air forced into the intake through the motion of the vehicle at speed. This is generally done with a scoop or duct of some type. A cone filter on some pipe is not a ram air intake; whoever sold your intake to you was calling it ram air for marketing reasons.

there are plenty of high power cars running k+n filters. but avoid foam ones like the plague......

[Digndoug]

really all of them will work the same.. but they all wont last the same length.. somthing like apexi might last longer then one with a cheap filter.. Iv used k&n before.. and right now im useing one of those chepo ones from e-bay.. same dang thing.. just dosnt last as long.

[Supersprynt]

Its not the same thing. You get what you pay for. You pay less, you get less airflow and less filtration. You may not notice anything, but its not the same thing.

[doGGy]

Well, then i searched for good AIR FILTER i read a loooooooot of material on the net, and had seen a looooot of independent test on A'PEXi K&N, HKS, Greddy and on and on.... THE BEST FILTRATION AND AIRFLOW has A'PEXi super airflow filter SECOND place is K&N. I bought my self A'PEXi just for the reason that it has best filtrating element, cuz if you take any of wet tipe filter put it in front of the light sourse, you will see a lot of small holes, that are going to be filled in with oil. Then oil dryes - dust will enter your intake... A'PEXi how ever has basiclly the same filtrating element structure as stock intake, but the airflow is better in that case.

Im not trying to force some one to buy this filter or somthing, but im just giving basic info, that helped me on desidion. Everyone hase different tastes and needs, so if you care about your engine life, then I suggest APEX'i...

As about airflow - best airflow = NO FILTER

Filter comparison

i was looking around the web on what filters to get for my home made CAI and i came across this page.

a note about cheap filters. I once bought a cheap white cone type filter for my old car and drove with it for a couple of months.. The filter stayed white and clean, so i was a little worried whether it filtered air well.. SO i sprayed some K&n filter oil on it, and 3 months later the air filter was all nasty. I don't trust those filters anymore, and i would not go cheap on something that protects my engine..

the original q was what one out of K+N, HKS, or TRD.

I assume hes talking about a panel filter and not an induction kit, although hell prove me wrong now lol

Im running a 250mm(10 inch) long Green filters cone filter (the one used in the peugeot 206 rally car) caused no probs as yet and the car is much more positive in acceleration

In my opinion, those tests are all BS,,,if you dump enough "fine particle" stuff on an oiled filter, it will of course eventually coat all the oiled surface so some stuff doesn't get trapped, but in the real world, no one would let it go that long, I have used foam air filters for years, they are the only thing I could use in my VW powered dune buggy, paper lasted about 3 days off-road, K&N not much longer, they would choke down so bad it was like driving with the choke stuck on, The foam ones (Amsoil) could go months with no problems, and no wear. They are one of the main reasons I eventually became an Amsoil dealer. As far as allowing wear or harming the air-flow sensor, I ran my 87 Mazda 626 for 162K miles with a foam air filter (and Amsoil synthetic oil) - NO problems. Lost all the water and cracked the head at 162k. When I took it apart, I couldn't measure any wear in the cylinders. the old rings were .003 out of spec, .017 in., limits were .008-.014. (the NEW aftermarket rings were .018!!!, had to buy OE Mazda rings - which were .011 exactly mid-spec, NO measurable wear in the cylinders )
So they can say whatever they want, I will still use the Amsoil foam air filters.
Reminds me of the old door-to-door vacuum cleaner salesmen, they would dump their "test dirt" under the rug and show how their vacuum could suck it up right thru the rug! then if you bought the unit, they would throw in a new bag cause they were nice, in reality it was to get their extra-special super fine laboratory test dirt back so they could re-use it on the next sucker.

IMHO, if you're going to use a foam/sponge filter, you might as well save some money and stick a panty hose at the end of your intake. It works just as well...

So which shapes of the air filter can make much more airflow??
Replacement drop in or Replacement mushroom filter (Like K&N)

It does sound beautiful since I ran the vent line or whatever that was going to the valve cover. Sounded horrible before that.
Seriously tho it made a huge difference in performance.

[Drocay]

i wouldn't spend money on the apexi unless i had turbo, for CAI just use a K&N cone thats what i got and its great. and it should be around 50-60 bucks.

[kuya1284]

[keefer37]

Where can I get one or the other for the quoted prices above?

[kuya1284]

[Hanyo]

it would be sweet to get a group buy for an apexi..

i'm sure everyone needs a new filter onces in a while..

[Negative]

I'm in if it would be a significant savings. I think freight would kill that deal though.
