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. This manifold, originally featured on the 2006-2011 Honda Civic Si, is known for enhancing high-RPM horsepower and delivering robust midrange torque, making it suitable for naturally aspirated or turbocharged applications. Compared to the stock PRB and PRC manifolds, the RBC intake manifold offers improved airflow past 5,500 RPM and sustains power effectively up to redline. This makes it a popular choice for K-series builds that frequently operate above 7,000 RPM. It serves as a common performance upgrade for various Honda and Acura models, including the 2004-2008 Acura TSX, 2003-2007 Honda Accord, and 2003-2011 Honda Element, equipped with K24A2, K24A4, and K24A8 engines. Compatibility extends to the 2002-2006 Acura RSX, 2002-2005 Honda Civic Si (EP3), and 2002-2006 Honda CR-V, which utilize K20A2, K20A3, K20Z1, K20A4, and K24A1 engines. Note that installations on K20 cylinder heads require cutting off the integrated coolant ports to clear the head’s water neck, a modification that is standard practice within the K-swap community. Additionally, a 75mm port-matched option is available for larger throttle bodies, such as the Hybrid Racing RBC Throttle Body, ensuring a precise fit and maximizing airflow and throttle response. This port matching is specific to the throttle body surface and does not extend to the head mating surface.
