Intake?

[filip9999]

well lets answer his question first.... the longer one draws cooler, denser air from the bumper, or "outside". the short ram usually sits in the same place the stock one sits and if u keep the bottom half of the stock box, the cooler air should be routed up to where the filter is sitting, i for one will not be spending the extra 100 bucks for a cold air intake, im in arizona and its hot here one way or another, also take into consideration that if u live in an area where it rains alot, sometimes the lower intake will get soaked in water and hydrolock ur motor, its not very likley but i have seen it happen, it ain't pretty

So a good header can make that much of a difference? I was told they make the car run pretty hot ? Is that true ? And what do they do to fuel milage ?

Hell yes a header can make a difference. How does 15-20 whp sound? The engine temp wont be any higher, but underhood temperatures will be. Its worth it though. Fuel milage won't be affected too much if at all.

I haven't seen dyno numbers, but I put a (cheap) RACTIVE short ram intake on my 94 prelude si. I noticed no difference. Then I bought a short ram for a civic at autozone, modified(cut a little of at a time) and atached it to the prelude short ram exiting where the stock air box was. You just have to cut the hole a little bigger,making sure sharp edges are covered to keep from damaging intake pipe. Build a box behind fender to protect from water. The reason that a regular cold air intake doesn't make much power is from the underhood heat heating the air intake pipe. With my scanner, I noticed the Air Intake sensor (AIC) was reading about 120 degrees. I insulated the whole pipe with foam tape and then aluminum tape to reflect radiant heat. Now my air intake temperater is reading the same as the outside air temp. The power increase was noticable. It looked good until I insulated it. Now it looks bad under the hood, but so what. Im going faster.

would u like to post that scanner data please, i am quite interested in ur discoveries

Find a freind with a scanner, Check your air temp. then do what ever you can to make it cooler. Check it again. Or get an infared laser thermometer(These are a fairly accurate way of checking air pipe temp).
When using a infared thermometer, you can pinpoint where the most heat is getting to you intake pipe. That way you can start there. I wrapped my whole pipe, which Im sure is not completly neccesary.
