Show original supplier description
The PRL Motorsports RBC Intake Manifold Adapter Kit is engineered to connect K24Z engines equipped with RBC or RRC intake manifolds to either the factory throttle body or a 70mm MDX/ZDX throttle body. This billet adapter kit ensures proper routing of essential coolant and vacuum ports, addressing common issues found with other adapter solutions on the market. This adapter kit is compatible with a range of vehicles including all 2012-2015 Honda Civic Si models, 2013-2015 Acura ILX 2.4L, 2009-2014 Acura TSX 2.4L, and 2008-2012 Honda Accord 2.4L. It is designed to fit all variant models, including 6MT, RHD, and International versions. Technical notes indicate that for K24Z engines using an RBC intake manifold, injector boring to the manifold may be required to utilize factory 9th Gen Civic Si injectors. Alternatively, standard K-Series (8th Gen Civic Si) style injectors or Acura RDX injectors can be used. For optimal performance with 70mm ZDX/MDX applications, port matching the intake manifold plenum is recommended. Important Note: This product is not legal for sale or use in California on any emission-controlled motor vehicle.
