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.
