Cold air intake? Yea or nay?

[jarydM]

I know it would take some additional hardware to get it plumbed into the filter box but I'd like to hear from someone who did it. This would allow the engine to draw air from the pressure bubble that forms at the base of the windshield while at highway speeds. Some of the muscle cars of the 60s and 70s had functional cowl induction. NASCAR uses the same theory but taps into the defroster intake just below the windshield. This can cause a bit more noise in the cockpit though.

unless you are constantly over 90mph, I can't imagine this being the case. Even the Cowl inductions of the muscle cars of old weren't able to utilize this. Nascar, yes, but we are talking about 120+mph

So you would take it from the cowl to the filter box and then back to the throttle body? Seems like a long trip.

Also the old muscle cars had an air filter sitting on top of a carb which is a better scenario for this than our setup.

Theoretically, you could pull the air out at the front of the hood as the entire scoop would be pressurized at speed. This would make the connection to the air box considerably shorter. I was hoping that there was someone here as crazy as I was that knew how to fabricate and had put a cowl induction hood to its proper use! Thanks for the replies.

What about these things?

I looked at them, 2 things.

1) your TB is a 4" hole, so get a 4" pipe.
2) those accordion type pipes still create a lot of turbulence inside, while it might be ok for a short distance, I wouldn't really want one in there, especially when you can do it with one straight pipe.

Not smooth enough. That flex tube has to many wrinkles. U want the best air flow/smoothest u can get.

Did you buy a whole intake kit and use just the pipe?

yeah, found a CAI kit on ebay for ~$40, and just used the pipe, the rubber connectors, and the screw clamps

So, you basically have what you get with the MIT, but for ~$75 less. Rock on.
