Honda RBC Intake Manifold - K-series / 06-11 Civic Si

This is the infamous K-series "RBC" intake manifold. It is found on the JDM Euro Accord-R and our US 06-11 Civic Si. This is comparable to a B-series Type-R manifold upgrade for a K-series. It yields better mid to top-end power inhalation over the stock DC5/EP3 Type-R 'PRC' and US RSX Type-S 'PRB' intake manifolds.

The RBC is also a highly popular upgrade with K-series legacy chassis swap scene (ie. 88-00 civic & 90-01 integra vehicles).

The RBC manifold is specifically designed and will only bolt-on to the following vehicle/engines, particularly because of the head design:

06-11 Civic Si (K20Z3)
04-08 TSX (K24A2)
03+ Accord (K24A1/A4)
03-08 Element (K24A4 

The RBC manifold is NOT a direct bolt-on for K20A/A2/A3/Z1 series engines but can be with a required modification. The water neck section must be carefully cut off in order to fit said engines.
