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.

Measures at 70mm and provides increased incoming air, which provides more usable power and torque.

BLOX Racing offers a throttle body adapter for Honda K-series enthusiasts wanting to use the RBC intake manifold but wanting to retain the drive-by-cable operation.

In a nutshell, the Honda RBC intake manifold is the best performing manifold for the K-series engine but is hampered by the factory’s electronic drive-by-wire system. Using the BLOX Racing throttle body adapter allows the enthusiast and engine builder to bolt on a BLOX Racing billet K-series or the OEM K20A2 throttle body onto the RBC intake manifold, providing quicker throttle response and intake airflow.

BLOX Racing RBC adapters are available in 62.5mm (stock size) and 70mm bores.

BLOX Racing billet K-series throttle bodies are available in 70mm and 72mm. K-series TPS are also available.

BLOX Racing Tuner Series throttle bodies are alternatives to its line of billet throttle bodies. These units are cast in aluminum and are direct-fit for the Honda B/D/H and F-series engines. The Tuner Series throttle body looks and feels like an OEM unit but definitely out performs it. The larger bore sizes helps to optimize incoming airflow and increases horsepower and torque. BLOX Racing Tuner Series throttle bodies each include a matching gasket.
