The Skunk2 Billet Ultra-Race Series Intake Manifold for Honda K20C1 / K20C4 engines solves the problems you will encounter when trying to push high boost to make Big Power. All Ultra Manifolds feature tapered runners with trumpet profiled entries and plenums that have been designed and optimized using CFD. Compared to the OEM plastic manifold, the Skunk2 Ultra Manifold has a larger plenum and runners for higher horsepower engines and won't come apart like OEM when boost pressure is turned up.

The manifold is designed with provisions to easily add and mount secondary port fuel injectors for high horsepower engine and turbo combinations. The Skunk2 Ultra runners are CNC machined from solid 6061 billet, while the plenum is cast from aircraft grade A356 aluminum and finished-off with our Signature Skunk2 Ultra-Series nameplate. The modular design of the Skunk2 Ultra Manifolds allows the plenum volume to easily be increased using simple spacers, and the runners to be freely ported for additional flow and volume. The versatility of this manifold allows enthusiasts and engine builders to tune the manifold combination to best suit their specific needs.
