Elevate your K-series engine's performance with Honda’s top-tier RBC intake manifold, integrated seamlessly with the Hybrid Racing package. This kit is designed for optimal functionality with K20Z3/Z4 or K24 engines.

Superior Performance with the RBC Manifold

The RBC manifold is renowned for surpassing the PRB and PRC manifolds across most of the rev range. While there is a slight drop in power at low to mid revs, the RBC manifold distinctly outperforms its counterparts from 5500rpm onwards. The accompanying dyno graph illustrates this, with the RBC manifold (red line) maintaining power generation up to the redline, contrasting with the PRB manifold (blue line) which starts to taper off at 7400rpm.

Drive-by-Wire to Drive-by-Cable Conversion Solution

The RBC intake manifold is equipped with a drive-by-wire throttle body. For those who prefer the drive-by-cable system in their K-swapped or K-equipped vehicle, an adapter is essential. Our K-series Throttle Body Adapter solves this issue, enabling the use of a PRB or PRC (K20A2 Type S and K20A Type R) style cable-actuated throttle body on an RBC manifold.

Complete Adapter Plate with Premium Hardware and Gaskets

The adapter plate comes with all necessary hardware, featuring a 64mm bore suitable for OEM-sized throttle bodies.

To ensure a leak-free installation, the kit includes essential gaskets: an Intake Manifold Gasket and throttle body gaskets for both the RBC and PRB/PRC interfaces. These high-quality Hybrid Racing Thermal Gaskets surpass OEM standards. The intake manifold gasket, made from a thermal-resistant polymer, minimizes heat transfer from the cylinder head to the intake manifold. Additionally, the throttle body gaskets are designed to reduce heat transfer and include a removable insert for transitioning from 64mm to 70mm bore size, accommodating aftermarket throttle bodies.
