QUOTE]has any body used an airfoil for the throttlebody? does it make a difference? Corvette America claims it can add 12 Hp.[/QUOTE]
I got mine with the K&N filter.
with the combination, the car did feel quicker especially on the highway when the wind speed kicks harder into the intake.
But then again when i changed my stock air filter it was black and in bad shape...
If you got the money your better off with a after market intake, one up from stock diameter.

It sounds like we are divided on this issue, huh? I am not sure if the gain will outweigh the effort, but I do appreciate the opinions. 1-2 hp is far from 12 hp, so I will probably not spend anymore time entertaining these thoughts. My new Lingenfelter throttlebody cover should bump me up to about 800 hp. LOL :lol: :yesnod:
