This amazing intake manifold adapter kit is a perfect fit for all 2012 - 2015 Civic Si models. It also works great with 2013 - 2015 Acura ILX 2.4L, 2009 - 2014 Acura TSX 2.4L, and 2008 - 2012 Accord 2.4L. It suits all variant models including 6MT, RHD, and international models. The Honda's RRC and RBC intake manifolds are among the best - flowing ones for the K - Series engine. For engines like the 2012 - 2015 9th Gen Honda Civic Si, 2013 - 2015 Acura ILX, 2009 - 2014 Acura TSX, or 2008 - 2012 Honda Accord with less - desirable intake manifolds, this adapter kit is a top - notch solution. It's needed for a manifold swap to route coolant ports and seal vacuum ports properly. Our billet intake manifold adapter kit smoothly adapts both the intake manifold and DBW or drive - by - wire throttle body. Note that the RBC intake manifold needs injector boring if you want to use factory - diameter 9th Gen Civic Si injectors; otherwise, use standard K - Series (8th Gen Civic Si) style injectors or Acura RDX injectors. For 70mm ZDX / MDX applications, port - matching the intake manifold plenum is recommended for best performance. Vehicles with RBC / RRC intake manifolds need specific intake systems. The kit includes a PRL Motorsports Intake Manifold Adapter Flange with hardware (PRL - HC9 - IM - KIT) and a PRL Motorsports Throttle Body Adapter Kit (PRL - HC9 - IM - STK or PRL - HC9 - IM - ZDX).
Using this intake manifold adapter kit is straightforward. First, make sure your vehicle is one of the compatible models, like the 2012 - 2015 Civic Si. When doing the manifold swap, use the adapter kit to properly connect the intake manifold and throttle body. It helps route coolant ports and seal vacuum ports. If you're using the RBC intake manifold, decide whether you'll need to bore the injectors for factory - diameter 9th Gen Civic Si injectors or use other types of injectors. For 70mm ZDX / MDX applications, take the time to port - match the intake manifold plenum for better performance. Always follow the included instructions for installing the PRL Motorsports Intake Manifold Adapter Flange and Throttle Body Adapter Kit. As for maintenance, regularly check the connections and seals to ensure there are no leaks. Keep the parts clean to extend their lifespan. If you have any issues, refer back to the installation guide or contact customer support.
