K24Z RBC/RRC Intake Manifold Adapter & Stock Throttle Body Kit

The PRL Motorsports K24Z RBC / RRC Intake Manifold Adapter Flange and Stock Throttle Body Kit is engineered to facilitate the popular swap of RBC and RRC intake manifolds onto K-Series engines that came equipped with less desirable intake manifolds. This adapter kit is crucial for properly routing coolant ports and sealing vacuum connections when installing these performance-oriented intake manifolds. Constructed from durable billet aluminum with a natural finish, this kit ensures a seamless adaptation of both the intake manifold and the Drive-by-Wire (DBW) throttle body. This adapter kit is compatible with K24Z engines (K24Z1, K24Z2, K24Z3, K24Z4, K24Z5, K24Z6, K24Z7) when used with an RBC or RRC intake manifold. It is designed to fit specific Honda and Acura models, including all 2012-2015 Honda Civic Si, 2013-2015 Acura ILX 2.4L, 2009-2014 Acura TSX 2.4L, and 2008-2012 Honda Accord 2.4L. The kit is compatible with all variant models, including 6MT, RHD, and International versions. Technical considerations for RBC intake manifold swaps include potential injector boring requirements for factory 9th Gen Civic Si injectors, or the use of standard K-Series (8th Gen Civic Si) or Acura RDX injectors. For optimal performance with 70mm ZDX / MDX throttle bodies, port matching the intake manifold plenum is also recommended. The kit includes the PRL Motorsports Intake Manifold Adapter Flange with hardware and the PRL Motorsports Throttle Body Adapter Kit (either PRL-HC9-IM-STK or PRL-HC9-IM-ZDX), ensuring all necessary components for installation are provided.
