*L* @ gm...unless your maf is bigger niether will do much..a waste of $$$$ and a tread....work with the exhaust this will add hp and gas mileage a winner @ both ends..put a nice set of 3:73 or 3:90's will wake the ole heavy car up. it is clear you have no plan on where your going with the car.. that is the first plan...bigger is not always better
