The only reason the AFE intake makes power on a dyno is because the hood is open (cool air) and even if it wasn't, the engine is not running for an increased amount of time to generate the heat to heat soak it like it would on the street..nevermind a track. It will only make power for about the first 5 mins of driving thats about it. Once that engine bay heats up, you'll lose power.

The stock intake wont sound as cool or have that throttle response, but will perform better overall. If there was a way to incorporate a large cone style filter with velocity stack in the OEM box, that would be the best solution.
