Honda RBC Intake Manifold – Performance Upgrade for K-Series Engines

The Honda RBC Intake Manifold is widely regarded as one of the best factory Honda manifolds ever produced for high-rpm performance. Originally found on the 2006–2011 Honda Civic Si and the JDM Euro Accord-R, the RBC manifold has become a go-to upgrade for K-series enthusiasts looking to carry power all the way to redline. Compared to the factory PRB and PRC manifolds, the RBC offers superior top-end performance by maintaining airflow and horsepower beyond 7400rpm—where the PRB falls off—making it ideal for street and track applications alike.

This manifold is a popular bolt-on performance upgrade for the 2002–2006 Acura RSX, 2002–2005 Honda Civic Si (EP3), 2004–2008 Acura TSX, 2002–2006 Honda CR-V, and K-swapped chassis using K20A, K20A2, K20A3, K20Z1, or K24A1 engines. Please note: some cylinder heads will require modification for proper fitment. Whether you’re building a naturally aspirated screamer or prepping for boost, the RBC intake manifold supports aggressive cam profiles and high-revving setups with ease.

On the dyno, the RBC shows proven gains over the PRB manifold from 5500rpm to redline, delivering the kind of mid-to-top-end power that turns lap times and wins races. Its short runners and higher flow characteristics make it comparable to the Type-R manifold upgrade on B-series engines, providing a factory-quality fit with aftermarket-level performance. If you’re serious about your K-series build, the Honda RBC manifold is a must-have for unlocking maximum power potential.
