Honda / Acura RBC / RRC Intake Manifold to Stock 2012-2015 Honda Civic Si Throttle Body Adapter Kit RBC to STK PRL Motorsports

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.

Often times these manifold swaps require a throttle body adapter. We offer a billet throttle body adapter machined from 6061 aluminum to seamlessly adapt a specific DBW or drive-by-wire throttle body to the intake manifold.

This throttle body adapter utilizes an O-ring to seal against the intake manifold and throttle body. A 1/8 inch NPT port and 90 degree fitting retains the factory EVAP Purge, but can also be deleted or plugged for a cleaner install. EVAP can be disabled with an engine tuner like Hondata FlashPro or KTuner.
