Designed to be 100% bolt on and plug and play, these larger bore units do not require any special modifications or rewiring. Once installed, the factory ECU will provide a "relearn" and dial in the new throttle body. Measures at 70mm and provides increased incoming air, which provides more usable power and torque.
