Skunk2 Ultra Race K-Series Center Feed Billet Intake Manifold

Designed for high-horsepower street and race Honda K series engines, this manifold features a single rail top-mount for 8-injectors. It uses tapered runners with trumpet-profiled entries and a large plenum optimized via CFD and dyno testing for maximum top-end power. The modular design allows plenum volume adjustment with spacers and runners can be ported. It includes a 90mm throttle body flange (standard 5.0 Ford bolt pattern) and a thermal gasket. Designed with an early style (PRB) intake manifold flange. Later style (RBC) flange engines require an aftermarket water bypass adapter. Not legal for sale or use in California on pollution-controlled motor vehicles.
