BLOX Racing throttle bodies for the Subaru FA20 engines are CNC-machined from high quality, billet aluminum. 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.
