Skunk2 Ultra Race Billet Centerfeed Intake Manifold – Honda K20/K24

Part Number: X307-05-0400

Product Description:

The Skunk2 Ultra Race Billet Centerfeed Intake Manifold for Honda K-Series engines is engineered for extreme high-horsepower street and race applications requiring maximum airflow, fuel delivery, and tuning flexibility. Designed specifically for serious naturally aspirated and forced induction builds, this billet manifold features a top-side 8-injector single fuel rail configuration combined with a centerfeed plenum layout for balanced airflow distribution and exceptional performance potential.

Precision CNC-machined billet tapered runners paired with a large modular plenum provide optimized airflow characteristics designed for maximum top-end horsepower and high RPM efficiency. Developed using advanced CFD analysis and extensive dyno testing, the Ultra Race manifold delivers race-proven performance for competitive applications.

The short high-volume tapered runners with trumpet-profile entries maximize airflow velocity and upper RPM power, while the modular plenum design allows users to increase plenum volume using optional spacers for additional tuning capability. The runners are also designed to allow further porting for custom high-flow race applications.

Built for racers and enthusiasts pushing the limits of Honda K20 and K24 engines, the Skunk2 Ultra Race Billet Centerfeed Intake Manifold combines premium billet construction, aggressive styling, and uncompromising performance.

Note: Does not fit K20C engine variants.
