Blox Racing billet throttle bodies have increased bore size while being lighter than the factory unit. They are 100% bolt-on, retaining all the factory functions such as drive-by-wire. A larger throttle body offers increased power/torque and throttle response by eliminating a choke point in the intake system. This allows for higher peak volumetric efficiency (VE) for turbocharged or supercharged applications.
After installation, the factory BRZ/FRS/86 ECU will perform a “relearn” for the new throttle body. Also compatible with aftermarket ECU’s.
Available in raw aluminum finish or anodized black.
