Skunk2 Ultra Race Billet Side-Feed Intake Manifold – Honda K20/K24

Part Number: X307-05-0350

Product Description:

The Skunk2 Ultra Race Billet Side-Feed Intake Manifold for Honda K-Series engines is engineered for extreme high-horsepower street and race applications demanding maximum airflow and fuel delivery performance. Designed specifically for serious naturally aspirated and forced induction builds, this billet intake manifold features a top-side 8-injector single fuel rail configuration for advanced fueling capability and clean engine bay integration.

Precision CNC-machined billet tapered runners combined with a large modular plenum deliver exceptional airflow characteristics optimized for maximum top-end horsepower and high RPM efficiency. Developed using CFD analysis and extensive dyno testing, the Ultra Race manifold is built to outperform conventional intake manifold designs in demanding racing environments.

The short high-volume tapered runners with trumpet-profile entries are specifically engineered to maximize airflow velocity and upper RPM performance. Its modular plenum system allows users to easily increase plenum volume using optional spacers while also allowing runner porting for even greater airflow and custom tuning capability.

Built for enthusiasts and racers pushing the limits of the Honda K20 and K24 platforms, the Skunk2 Ultra Race Billet Side-Feed Intake Manifold delivers race-proven performance with premium billet construction and aggressive styling.

Note: Does not fit K20C engine variants.
