Easy answer!Given the backorder of the AFe closed intake, the question should be asked: What benefits you more = Cold Air or More Flow?
Since the formula is for each 7 degrees warmer air you lose ONE horsepower. If your engine needs an additional 300 CFM to make 10 more horsepower then the solution is more air.
Factory air intakes are designed PRIMARILY to reduce NOISE - not make horsepower. If you're trying to go as fast as you can then making sure your engine can get ALL the air it can. MORE AIR FLOW IS THE SOLUTION. PERIOD!
In the 60s and 70s a LOT of car manufacturers had COOL cold air intakes that had openings in the hood or scoops and even scoops that popped up to keep the air intake cool. EVERY ONE of the owners of those cars, when at the dragstrip, took those COOL air intakes OFF their car and put on a 360 degree open air filter on top of their carburetors. The factory cold air intakes were restrictive and nobody gave a damn about "underhood heat" in order to go as fast as they could.
A dyno CAN NOT simulate the effect of air pressure built up at the front of a car doing 20, 40, 60, or 80 MPH - that air pressure helps to feed the intake.
