Skunk2 Ultra Race Billet Runners with Fuel Rail – Honda K20/K24

Part Number: X907-05-0350

Product Description:

The Skunk2 Ultra Race Billet Runners with Fuel Rail are designed for builders who already have an Ultra Race plenum or want to custom-build a high-performance intake manifold system for Honda K-Series engines. Engineered for extreme horsepower applications, this setup delivers maximum airflow efficiency and advanced fueling capability for serious street and race builds.

These billet runners are part of Skunk2’s Ultra-Race Series and are CNC-machined from high-grade aluminum to ensure precision airflow dynamics and durability under high-boost conditions. Featuring tapered, high-velocity runner design with trumpet-style entries, they are optimized using CFD analysis and extensive dyno testing to maximize top-end horsepower performance.

This configuration supports a top-mounted single fuel rail system for 8 injectors, allowing for advanced fueling setups required in high-power forced induction and race applications. The oversized plenum-ready runner design prioritizes high-RPM efficiency and maximum airflow capacity.
