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

In a nutshell, the 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 builer 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.
