BLOX Racing Honda K-Series 62.5mm Bore Throttle Body Adapter (RBC Manifold)

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 one of the best performing intake manifold's for the K-series engine but is hampered by the factory's electronic drive-by-wire system for K-swapped golden era vehicles.

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.
