SO a buddy of mine works ina metal shop, and just recieved some primo scrap metal, nicely polished stuff (dont ask why its scrap), and has agreed to make me a Cold air intake. Now, since im building it myself, i can place the end of it anywhere, and i was wondering where the "best" spot is. I know the further away from the engine the better (to a certain degree anyways... the longer the tube, the harder it is to suck air), but anywhere in specific ? Im concerned about getting rain in there, as i live in vancouver BC (one of the rainiest cities in canada). Any feedback would be amazing, as im still a car newbie.

I was under the impression that a bypass valve was used in conjunction with a turbo ? Are you saying that it has a secondary function applicable to my case (i dont have a turbo.Its a '94 ST)? Also, can you clarify what you mean by too long of throttle response ? Do you mean that when i hit the gas, the longer the pipe is, the longer the delay till i feel any power ? (Please excuse my limited engine knowledge, im learning still )Thanks for all your replies!

You are thinking of a Blow off valve, which can also be called a bypass valve, but not what we are talking about.

What the intake bypass is, is a secondary air filter on your intake piping. Generally put at the first Coupler on the intake. (minus the one on the throttle body, about where my Distributor is in the pic below)If for some god-awful reason your main filter is submerged, or is clogged with water, the bypass valve one will continue bringing in filtered air, preventing hydrolocking your engine and saving the day!

This is how my intake is set up..

I live in Washington, where we have rain for a good... oh. I dont know...1/3-1/2 the year. No problems for me, but when I get my coilovers installed I am going to need to go get one.
