Talking So i have a crazy idea for performance.

Okay, call me crazy but here it goes. For those who know how an intercooler is set up for turbocharged engines, my idea is quite similar. Designing an intake setup that looks exactly like an intercooler, but is only an intake. The setup would have 2 tubes like an intercooler but would both run to where you would traditionally plug in an aftermarket intake and they would merge into one pipe. The "Intercooler" intake setup would scoop the air through the front of the car, the air being colder and would feed into the car. Is this idea stupid?

Not stupid, but there are plenty of after-market "Air Intakes" available. Colder air is denser and stokes the fire better. On a turbo, the compression of the air increases its temperature, and the intercooler partially compensates for this. Some older ideas included a small spray of water into the intake which also cools the inflowing air. It's a common experience that the engine "seems to go better" on cold foggy mornings and people try to recreate this.

A cold air intake will basically do that, as the filter is in the inner fender.

If you do'nt try it we may not know for sure. It will require dyno time for proof and that can be somewhat costly.

Apart from having a more complicated arrangement of tubes, your idea (being a passive device) would not be better than a simple air intake sucking air from a cooler spot.

Air intakes need to eliminate rain, dust etc., and high performance cars with direct air intakes (no screens or filters) have sometimes come to grief by sucking in road debris. I saw one car (Jaguar, I think) blow an engine due to a small piece of gravel.

Its a good idea, but its not a practical one. It wont work like you think it will. It wont pull any more air in that your engine allready does, and an intercooler only cools air back to the ambient temp, which is what your car pulls in allready. Assuming your filter is not stuck wide open in the closed engine area.

If this was to work to the degree of use, you would have to cool the intercooler alot more than with air flow moving past it, you would need like meth or something, or a water/air intercooler system that uses cold water to cool the air. But again, its so much work to see little if anything of a gain, its not worth it.

Smile Crazy ideas

It would work but as has been pointed out you could get the same benifit fom a cold air intake system. Cost less and easier to install. Just dont do like most of the Honda's I have seen with a cold air intake that leave the filter sitting in the engine compartment. The best setups have some way for the filter to be pulling in fresh air outside the engine compartment.
I knew a guy who had a Camero drag car, the intake was the kind with runners over the valley and had a set of dams made of sheetmetal so he could ice the intake manifold between rounds. It gave him a couple tenths of a second in the quarter, so cooler air definately does help performance.

Well i was thinking about buying a cold air kit off KFX (The one you put together yourself) and seeing if i can run that to sit on the left side of the bottom grill of my bumper, and getting the Weapon R foam filter with the poly guard around it

Sounds like a plan. Just be careful how low you place the inlet/filter. You can pull in water and lock up your engine in the rain going through a puddle. Ask me how I know this
