Any true cold air intake for fd?

Vettes have vararam and many other kits.I am unhappy with my apexi intake. Its very warm after just a few minutes of driving.Is there a way to run custom hoses and filters next to the headlight by the the coolant container .There is a nice vent there if you remove that plastic piece in the front bumper. I was thinking of cutting a hole along side the headlight and brackets and feed it in front of the coolant container .If thats not a good idea maybe a scoot hood with a custom inside scoop to feed air to the intakes.Or just buy a m2 type of airbox.Someone here has got to have a better way!

Get a sleek headlight kit, with no covers! All the cold air you could ever want.

I dont have his airbox mod, but I would recommend it. IMO, it should help with any type of CAI, stock airbox or aftermarket.

Er, while you're at it, you might as well drive around without the front bumper or without the hood.

Its a kick *** plastic intake piping that runs thru the nose of a c5 and gives it true cold air.It knocks off up to .5 in the 1/4 mi and a increase of up to 5 more mph thru the traps.If fds had a cold air intake like this our results might even be better than the c5s,because of our dual or single turbo applications.

There's someone on this forum that did something like that actually. I can't remember his post so you might have to search. I think he ran a single turbo and ran a welded aluminum pipe to the area where the 2nd oil cooler would be (passenger side). He had some sort of ducting system to that side of the bumper and integrated some sort of filter into it. A lot of ppl ragged on him for it though because something that low would suck up a lot of the ambient heat off asphault, not to mention suck up water and all kinds of crap.

Wouldnt putting a cold air intake on a turbo charged car be kinda pointless? I mean the second the air hits the turbos, its going to get baked. I think it would be more benneficial to get a really good intercooler, which is down stream of the turbos. I would think you would just want to get the least restrictive, but still good fileration intake.

Deep water ingestion is only a problem if a c5 goes thru or sits in a puddle of 10 inches or more. i would welcome the temps off the road as compared to my hot engine compartment.

c,mon doesn't anyone notice how much stronger our fds run when its colder outside! A true cold air intake+ a good IC would make a huge difference in our HP numbers,not to mention maybe a little more miles out of our engines. Can i get a amen!

Coolvette, the CAI is sufficient for this car IMO. The problem is that you're running an open air intake.

I am thinking of altering my sccot hood so the air from the scoop goes directly on to the UIM.
This may help since the UIM retains alot of heat.

That would be great if he adds feedback to this thread. If not, I'm gonna have to go and search for his old one.

Amen brother.

You are either going to have to make it yourself or try the M2 and rotary extreme type boxes which are kinda nice but a bit pricey.

I run an adam_c type of mod on the stock airbox that I've been doing to all my cars since back in 87 or so when I started driving.

Being colder outside and having a cold air intake are two completely different things.

The reason you don't see too many cold air intakes/boxes, is that once you have a quality IC, the intake doesn't really matter all that much. Your intake temps AFTER the IC are more important than your intake temps before your twin turbos. The difference in temps before the turbos doesn't really show that much of a difference after being heated up by the turbos. If you were to have a 10 degree difference at the intake, that doesn't mean you'll have a 10 degree difference at the throttle body.

Cold air is always good... but I think that what folks have found is that often due to the constraints of the FD design, you rairly get a high flow of cold air... it ends up a pinched little opening.... hence the usual negligible difference between a cooler, but more restricted flow of air, and an open, hot air filter. When turbos have to suck through a mcdonalds straw to make pressure, that creates extra heat as well.

So, the short answer is, cold air is good, but MORE air is just as good or better. Ideally you'd have both, but thats tough with these cars.
