well ive been trying to search for a cold air intake for my car and seem to not find one and a lot of people say i have to custom my own if i want to get one. so is a regular air intake most effective for the fcs then a cold air intake?

Cold air increases HP period. About .12HP per degree in F. My studies have shown quicker throttle response and quicker power curve line with a shorter peak, dropping quickly with a short intake system "cold air / ram air/ upgraded filter" an a longer drawn out curve with higher peak and more gradual drop using a longer intake such as going under your fender or in front of engine bay. This has been debated and coved allot. Search some more for other replays that may help you. Most members with N/A's here fab there own.

a CAI for a 92 prelude fits with slight modification to the car, check eBay.

I made mine out of some ducting from home depot. Total: about 7 bucks...

In that case, you may as well not bother with a CAI since the air is compressed into the turbo and heats up anyway. So just slap a cone filter in there somewhere. If you want cooler air going into your engine, get a bigger better intercooler. But you can still try to fab something up to get cool air to the filter if you want to.

Why wouldn't you bother? That's just ignorant thinking honestly. The colder the air that is brought in, the colder it will be overall even after being compressed and heated up. If you bring in say 80º engine bay temp or 60º (just some random numbers, I really have no idea what the temps in the engine bay get to) outside air, which do you think will be lower in temp after being compressed? And after that it goes to the intercooler, right? Well which do you think will still end up being cooler after going through the intercooler?

The point is, true cold air intake will result in cooler intake temps no matter what when comparing to just an open cone filter sitting in the engine bay.

i just put a chunk of dry ice on my top mount intercooler and there ya go cold air

well, it would be nice if that actually worked all the time. driving around town and jumping out of the car at stop lights to put ice on the tmic is not on anyone's want list. hahaha

Yes, I'm aware that cold air at the filter will result in colder air after being compressed than if it were sucking in hot air. I don't know how much of a change that would be. What I'm saying is if he wants cooler air going into his engine he should concentrate on a better intercooler first. For all we know, sucking in cold air on a turbo may make a small, even negligible, difference. Heck, it doesn't even make that much of a difference on an N/A as it is. When I said I wouldn't bother, I meant I would drop the money on something else, rather than a CAI (for a turbo, I'm working on a CAI myself for my N/A ).

For a turbo car it'd cost about 40-50 bucks max to do it yourself as long as you have basic tools, that's hardly a big deal at least in my mind.

yeah thats why i would only do it at the track kept the TMIC real cold and helped from the hot engine bay, but the only downside is that a big chunk only lasts about 30 min. its also cool how the smoke comes from the hood scoop may look like your car is overheating but you know better.

you could just tell the ricers that you freeze your engine before you installed it so it always stays cold

so does it matter on wat kind of filter to get? (expensive assuming high quality ones or just plan 30 buck ones that fit universaly)
