Honda RBC Intake Manifold f-series The Hybrid Racing Dipstick sitsHere is a kit to equip your K series with Hondas finest intake manifold design, and along with it, a Hybrid Racing package to make it work with your K20Z3 Z4 or K24. The RBC manifold outperforms the PRB and PRC at almost all parts of the rev range. There is a marginal power loss in the low to mid revs, but from 5500rpm onwards the RBC is a clear favorite. The dyno graph above shows the difference. The red line is the RBC manifold and blue is the PRB.
