2012-2015 Honda Civic Si RBC/RRC Intake Manifold Adapter Flange w/Hardware

It's no secret that Honda's RRC and RBC intake manifolds are some of the best flowing intake manifolds available from Honda for the K-Series engine. RBC and RRC manifold swaps are a popular solution for engines equipped with less desirable intake manifolds like the 2012 - 2015 9th Gen Honda Civic Si, 2013 - 2015 Acura ILX, 2009 - 2014 Acura TSX or 2008 - 2012 Honda Accord. This manifold swap requires an intake manifold adapter to properly route coolant ports and seal vacuum ports. Our billet intake manifold adapter kit seamlessly adapts both the intake manifold and DBW or drive-by-wire throttle body to the intake manifold.
