RBC Intake Manifold

The Honda RBC Intake Manifold (part number 17100-RRB-A00) is a highly regarded OEM performance upgrade for K-series Honda and Acura engines. It was originally equipped on the 2006-2011 Honda Civic Si and is known for delivering significant high-rpm horsepower gains and strong midrange torque, making it suitable for naturally aspirated or turbocharged builds. Compared to the factory PRB and PRC manifolds, the RBC intake manifold provides increased airflow beyond 5,500 RPM, carrying power to redline. It is a common upgrade for vehicles such as 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. When installing this manifold on K20 cylinder heads, it is necessary to modify the integrated coolant ports to clear the head’s water neck. This is a common practice within the K-swap community. For those using larger throttle bodies, Hybrid Racing offers a 75mm ported RBC intake manifold option, CNC-machined to precisely match larger throttle bodies.
