Blox Racing K-series dual-pattern throttle bodies fit both PRB/PRC and RBC/RRC intake manifolds without the need for a throttle body adapter plate.

Each is CNC machined from billet aluminum. Precision machined butterfly plates proper and consistent opening and closing. New throttle springs provide crisp response each time the engine is revved. Units are anodized to resist corrosion and are available in black and silver finishes.

The IACV can be used or blocked off for full race applications. Throttle bodies include hardware and new gasket. All factory sensors can be reused without any modifications.

Available in 70mm. The larger throttle bodies offer increases in airflow resulting in additional horsepower and torque gains. 

Throttle bodies include gasket and mounting hardware.
