Hybrid Racing K-Swap RBC Intake Manifold Package (K20A/A2/A3/Z1) 435i Best fit for ClassicsHere 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 K20A A2 A3 Z1. Note that coolant passages will need to be cut off to make the intake fit on these cylinder heads. 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.
