cold intake

Well , Injen runs their INTAKE to the center of the grille area , AEM runs their the other way to the wheel well area , or JWT Popcharger is a short air tube system with the filter up in the engine area. There are more but HP Gains are minimal at best .

They will do the same with either an At or MT. Do a search on this and you will find tons of info. None are really going to give you any real performance gains. Maybe 4-5 hp. I would go Injen, JWT, or K&N CAI. Stay away from AEM. It has been said to possibly lose hp.

JWT Pop Charger is still my personal fav...
