K-Series Intake Manifold

The Honda 17100-RRB-A00 is a genuine OEM intake manifold, specifically the RBC model. It is designed as a direct replacement for 2006-2011 Honda Civic Si models and is a well-regarded performance upgrade for K-series Honda and Acura engines. Originally found on the 2006–2011 Honda Civic Si, this manifold is known for delivering strong high-rpm horsepower and midrange torque, making it suitable for naturally aspirated or turbocharged builds. It flows more air beyond 5,500 RPM compared to the factory PRB and PRC manifolds, carrying power to redline. This makes it an ideal choice for K-series builds that frequently operate above 7,000 RPM. The RBC manifold is also a common upgrade for various K-series applications, including the 2004–2008 Acura TSX, 2003–2007 Honda Accord, and 2003–2011 Honda Element (with K24A2, K24A4, and K24A8 engines). It is also compatible with the 2002–2006 Acura RSX, 2002–2005 Honda Civic Si (EP3), and 2002–2006 Honda CR-V (featuring K20A2, K20A3, and K20Z1 engines). However, installation on K20 cylinder heads requires cutting off the integrated coolant ports to clear the head’s water neck, a modification that is common in the K-swap community. A port-matched option is available, featuring a CNC-machined 75mm throttle body flange for compatibility with larger throttle bodies like the Hybrid Racing RBC Throttle Body. Note that this port matching is specific to the throttle body surface and does not include porting where the manifold mates to the head.
