Overview

The PRL Motorsports RBC Intake Manifold Adapter Kit is designed for the 2012-2015 Honda Civic Si, 2013-2015 Acura ILX 2.4L, 2009-2014 Acura TSX 2.4L, and 2008-2012 Accord 2.4L. This billet adapter kit seamlessly connects your intake manifold to a drive-by-wire throttle body. It also properly routes coolant and vacuum ports, addressing common issues with other kits.

The adapter facilitates the use of RBC or RRC intake manifolds on K24Z series engines. For optimal performance with 70mm ZDX/MDX applications, port matching the intake manifold plenum is recommended. Injector fitment may require modification to the manifold when using factory 9th Gen Civic Si injectors.
Show original supplier description
The PRL Motorsports billet intake manifold adapter kit is engineered to connect RBC, RRC, and Skunk2 Pro Series intake manifolds to either the factory throttle body or a 70mm MDX/ZDX throttle body. This kit is specifically designed for K24Z engines and ensures proper routing of coolant and vacuum ports, a crucial feature often overlooked by competing products. This adapter 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 accommodates all variant models, such as 6MT, RHD, and international versions. Technical notes indicate that utilizing RBC or RRC intake manifolds requires specific intake systems. For those employing factory-diameter 9th Gen Civic Si injectors, the intake manifold itself will require injector boring. Alternatively, standard K-Series (8th Gen Civic Si) injectors or Acura RDX injectors can be used. For enhanced performance, port matching the intake manifold plenum is advised when using 70mm ZDX or MDX throttle bodies. Note: This product is not legal for sale or use in California on any emission-controlled motor vehicle.
