cold air intake?

[Draco-REX]

Most cars have a ducted airbox. Hell, my tow vehicle, a 1991 E-530 ambulance has a pipe that goes from the front of the nose near the headlight to the engine's intake. My '86 Corolla Deluxe had one too. "Cold Air" has been a gimmick in the aftermarket for a VERY long time.

How I wish I could stress this point even more.

Ford has had open-element K&N style filters on Mustangs for a while just because people think they're better.

To be fair, they usually do it right and have a heat shield that forms an airbox when the hood is down. There's usually an opening to the fender as well so it gets cool air.

Open the PDF doc in the first post and scroll down a bit.

The air behind these headlights will be in a vacuum (if I'm not mistaken) and there's a fair amount of bends so I think there's still gains to be had.

Even just getting some clean air to the area near the head light would help as it looks like that area will be in a vacuum while driving. A cut out in the front bumper foam and a scope to divert some air from the grill opening up to the head light area might be all the gains we're going to get though.

The diagram is a lot different than the WRX/STI. Its exit is pointing sideways for one, which makes it not a ram air intake. Also, as far as gains go, how restricting the actual airbox is will dictate how much power can be gained, if any. On the WRX/STI it isn't that restricting, until you are flowing a 25+% more air than stock. On this car, I don't think anyone here can really claim to know either way.

I'll say whatever I damn well please and not back it up with any logical evidence or proof, because this is the internet.

no you wont

I'll wait til they post a dyno plot... IF they post a dyno plot... Good luck.

Exactly. Let's wait and let the intake manufacturers post dyno sheets before we all jump to the conclusion that there is no power to be had.

I'm sure intakes will make some power on a dyno. Unless it's a significant amount, I doubt the dyno evidence offered will show any gains outside the normal variance of any given dyno comparison. The intakes that do show big gains might do that by manipulating the maf sensor, making the car run lean for a while before the ECU compensates or the engine detonates. Guess we shall see soon. I'm going to guess TRD/SPT will release an intake that adds no power, doesn't manipulate the maf and makes cool sound effects. I'll probably buy that one!

Trd filter is out and intake system is coming in around August

Factory Box with K&N filter inside done!

Well for me at least

Sweet, now I just need to wait for my car to be delivered!
