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

If you're swapping in a Honda K-series engine or upgrading your intake manifold to an RBC unit on your Acura RSX, TSX, or Honda Civic, you'll need to adapt your throttle body. This adapter from BLOX Racing is designed to bridge the gap between a 62.5mm throttle body and the RBC intake manifold, ensuring a solid seal and proper airflow.

This adapter is made from a durable material that holds up well to engine bay temperatures. It's a straightforward part that helps make your intake swap go smoothly. Getting the right seal here is important to prevent vacuum leaks, which can cause rough idling and poor performance. This adapter is specifically sized for 62.5mm throttle bodies, making it a direct fit for that common setup.

This part is designed to fit a range of popular K-series powered vehicles, including models like the 2002-2006 Acura RSX, 2004-2008 Acura TSX, and 2002-2011 Honda Civic. It's a simple but necessary piece for many engine build and swap projects.
