Genuine Honda RBC Intake Manifold K20Z4 Uncut

The RBC Intake Manifold is one of Honda's best intake developments for the K20 engines. Found on the Accord Euro R CL7 as standard, the engine was one of Honda's most powerful of the K20 lineup and is now available for all K20 engines and will fit the EP3, DC5 and K-Swaps with ease. The RBC manifold out performs the PRB (uk spec) and PRC (jdm spec) manifolds almost everywhere. There is a little loss in power from low to mid range rpm but from the 5500rpm point and up the RBC shows its true colours and has a gain averaging 10-15bhp with mapping. Out of the box, the intake manifold does need a small amount of modification to fit K20A/A2 applications but we have done this for you so it is a direct bolt on. Please note that this intake manifold is longer than the stock prc/prb item. EP3'S will need to trim the slam panel to suit. A throttle body adapter is also needed to use k20a mechanical style throttle. Please see inlet adapters.
