Skunk2 Honda and Acura Ultra Series Race Manifold F20/22C Engines

Fitting the 2000 to 2009 Honda S2000 F20C and F22C, our patented Ultra Race Intake Manifold features massive increases in airflow. Ultra Race Series manifolds were developed using the latest in Computational Fluid Dynamics software and years of R&D with our legacy Pro Series Intake Manifolds to provide the ultimate modular solution to suit your needs.

The three-piece design allows removal of the intake plenum to access the internal 87mm velocity stacks and runners. This gives the ability to clean and port the manifold where necessary to allow for even larger amounts of air flow. Additionally, separately sold plenum spacers act as sandwich plates that can be added between the manifold and the plenum to increase overall plenum volume.

Built in accessory National Pipe Thread (NPT) ports allow for easy vacuum sourcing, and provisions for secondary fueling allow the intake manifold to easily support an additional set of injectors and fuel rail.

Our high performance Ultra Fuel rail is included! This satin black anodized rail features AN Fittings at both ends and a higher flow volume than OEM to allow for larger amounts of fuel and more consistent flow.
