the air foil seems like a good idea but i didnt feel any difference at all with mine. in fact upon closer inspection i noticed the air foil actually blocks all air flow to the PCV system which is not good even if the air foil was a proven 10 rwhp.

if you want better throttle response then get a larger TB... you wont necessarily get more power but you will feel quicker at least.

 

THanks to everyone who replyed

 

I'am not sure yet, but I think my air foil is to blame for my bad gas mlg i've been getting since I installed it. I wonderig if thats ever been tested? because it blocks several functions of the TB and restricts the air going into the IAC as well.

 

useless unless your pushin big power
