L67 ported throttle body from zzp performance in excellent condition used for only two months. Like new! Includes all sensors it came with plus mass air flow sensor! Also included is a phenolic spacer from zzp ( additional 50 value) for free!! This setup really makes a noticeable power increase in a supercharged 3800! And makes it sound even meaner! No modifications needed it's plug and play!! Not an aftermarket clone this is a oem throttle body that has been ported
