Hybrid Racing K-Swap RBC Intake Manifold Package (K20Z3/K24)

Here is a kit to equip your K-series with Honda’s 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. The PRB makes power to 7400rpm before falling off while the RBC keeps making power all the way to redline.  The RBC intake manifold comes with a drive-by-wire throttle body, meaning if you want to retain the drive-by-cable system for your K-swap or K-equipped vehicle, you will need an adapter. Our K-series Throttle Body Adapter addresses this problem by letting you use a PRB or PRC (K20A2 Type S and K20A Type R) style cable-actuated throttle body on an RBC manifold.  All hardware is included with the adapter plate. Plates have a 64mm bore
