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, such as 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. PRL Motorsports' billet intake manifold adapter kit seamlessly adapts both the intake manifold and drive-by-wire (DBW) throttle body to the intake manifold.

RBC intake manifolds require injector boring to utilize factory-diameter 9th Gen Civic Si injectors; otherwise, standard K-Series (8th Gen Civic Si) style injectors must be used. Acura RDX injectors are also a popular solution. PRL also recommends port matching the intake manifold plenum for 70mm ZDX/MDX applications for optimal performance.
