TPiS 58MM throttle bodies start out as a solid chunk of 6061 T6 heat treated aluminum (not a casting). They feature a re-designed throttle linkage cam for better throttle control and feel. They also sport a black oxide finished-turned, ground and polished throttle shaft supported by sealed ball bearings for a super long lifespan, and CNC machined throttle blades (not stamped like others) for a precise fit. Bodies are anodized 'Carbon Black' for a long lasting finish. A billet IAC housing, TPiS ID plate, and gaskets are included. This throttle body flows nearly 1100cfm and are great for engines making 450-550hp.
