Thank you for helping me understand my dilemma! I was wondering why my car goes backwards after installing this OPEN intake! AFE claims you gain 14 HP with this intake, however I estimate with all that hot under-hood air it reduces the HP by 200-230 HP - THAT EXPLAINS WHY THE CAR GOES BACKWARDS NOW! Do you think if I install a 250 HP nitrous kit it will start going forward again?That might be true, but whatever gain you got was lost by removing the top cover of the air box. Of course the Takeda intake with the open top is by design.
