IS THE FOLLOWING CORRECT?
A cowl induction hood creates a vacuum in the center bottom of the windshield. This vacuum allows hot engine air to escape easily. Colder air can then replace the hot air making the engine perform better. This combined with a CAI should increase mpg and overall performance.

 

i believe thats right, although im wondering if it would be worth me putting a cowl on my truck...any ideas?

 

Its always worth it to put one on your truck. Even if its only for looks. haha I think they are awsome and I think your right moose. It at least it sounds good.

 

any idea on how much a paint job would be for the hood to match everything else? and whats the pros/cons of fiberglass/steel?

 

get a steel hood, GM goodmark. i got one on my truck and everything is lined up perfectley.

 

I'm in the process of getting an estimate for a steel cowl hood and bushwacker pocket fender flares. The estimate includes everything painted to match my truck and installation.
I was told fiberglass hoods are difficult to line up and just don't look as good as steel. Matter of fact, the guy giving me the estimate said he would't even do the fiberglass hood!

 

Fiber glass hoods flex with the heat and cold either from the weather and or engine. However they are a whole hell of a lot lighter than a steel hood.

 

just seems like the pros of steel outweigh the cons

 

I am in agreement with you on the pros of teh steel plus my good friend had a fiberglasshood on his 1990 chevy and said he would never buy one again, but a steel 1 he would.

 

I want a cowl hood real bad. Mostly just for looks but if I see any gains in anyhting else I will be thrilled.
