Description

Fitment:

- 2002-2006 Acura RSX (K20A2, K20A3, K20Z1) - requires coolant port modification

The Honda RBC Intake Manifold (part number 17100-RRB-A00) is one of the most respected OEM performance upgrades available for K-series Honda and Acura engines. Originally found on the 2006-2011 Honda Civic Si, this manifold has earned a reputation for delivering outstanding high-rpm horsepower and strong midrange torque-making it ideal for aggressive naturally aspirated or turbocharged builds.

Compared to the factory PRB and PRC manifolds, the RBC intake manifold flows more air beyond 5,500 RPM and carries power all the way to redline, especially beneficial for K-series builds that live above 7,000 RPM. This is why it's commonly chosen as a performance upgrade for the 2004-2008 Acura TSX, 2003-2007 Honda Accord, and 2003-2011 Honda Element with the K24A2, K24A4, and K24A8 engines.

The RBC 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, when installing this manifold on K20 cylinder heads, you'll need to cut off the integrated coolant ports to clear the head's water neck. This modification is common practice and well-documented in the K-swap community.

Hybrid Racing 75mm Ported RBC Option
If you're running a larger throttle body, check out the Hybrid Racing 75mm Ported RBC Intake Manifold. This modified version of the RBC is CNC-machined to open the throttle body flange to 75mm, making it a perfect match for the Hybrid Racing RBC Throttle Body (HYB-THB-01-05). Each manifold is precision-machined to ensure a clean, accurate surface for a seamless fit. The result is a professional-grade port match that maximizes airflow and throttle response for street or track use.

*Please note port matching is only on the throttle body surface, this option does not port the intake manifold where it mates to the head.
