I crafted a cold air intake/ram air in my 88' Firebird 305 with a section of that aleuminum dryer hose. I ran it up through the fender and the frame to the stock intake hose. The other end comes out under the hard plastic under teh nose. I'm not sure if it worlk very well. I can remove the black plastic intake that came stock and put the two together. Anyway, I was going to ask what the cold air intake/ram air does for power and gas mileage. I don't want to use this if it is just using tons of gas. If anyone can list the pros or cons on this I would appriciate it alot. I was thinking of taking it back out otherwise.

 

4% gain over an open element at 60mph. your car wont use more gas. that computer set. your car doesnt inject gas based on air taken in, its based on tps sensor and other sensor related charts built into the chip.

 

well... on the stock aircleaner i wouldnt say its better than an open element at all but it is way better than stock and youll actually increase your gas mileage since the engine is now more efficient at what it does. Its taking in denser air thus creating more power thus requiring you to push the gas pedal down less to move the car the same distance.

I used to run that same ram air setup when i first got my car it was a big improvement but didnt compare to the open element. Open element would save you more gas
