RBC and RRC intake manifold adapter kit for the 2012 - 2015 9th Gen Honda Civic Si, 2013 - 2015 Acura ILX, 2009 - 2014 Acura TSX or 2008 - 2012 Honda Accord. This kit properly routes coolant and vacuum ports unlike other kits on the market.

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.
