Amx1397 Is right But I still ended up being a Guinea pig and tried it out and despite being snake oil it did deliver way more air than I expected giving me back low end power increasing top end on 91 but causing the car to go Lean to counteract it I put a Sonoco super Sport 100 octane because of the excessive air afraid of knocking in the engine but when I did that the jet maf sensor with the 100 octane and my stock ram air style crossfire intake plus the larger throttle body woke up the car and pulled hard enough to beat a 392 dodge charger from a 60 roll and leave him 3 cars back and keep up with a m4 cs in the canyons so u know what I'm happy next mods eurocharged tune bigger fuel pump needswings headers fuel regulator air fuel ratio gauge and down pipes I'm gonna get all the hp I can get weather its 6 hp or 10 hp it adds up
