Technical Notes:

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.

RBC intake manifold requires injector boring to the manifold itself 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. We also recommend port matching the intake manifold plenum for 70mm ZDX / MDX applications for optimal performance.
