Throttle Body Adapter - Honda K-Series RBC Manifold


WARNING: Cancer and Reproductive Harm www.P65Warnings.ca.gov

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.


  • Adapts cable driven RSX Type-S throttle body to RBC manifold
  • Includes gaskets, hardware, and port plug
