Skunk2 Ultra Race Billet Runners with Fuel Rail – Honda B Series (All)

Skunk2 Ultra Race Billet Runners with Fuel Rail – Honda B Series (All)

Part Number: X907-05-0100

Product Description:

The Skunk2 Ultra Race Billet Runners with Fuel Rail for Honda B-Series engines are engineered for high-horsepower street and full race applications where maximum airflow and advanced fueling capability are required. Designed for builders using an Ultra Race plenum or custom intake manifold setup, this system provides a modular solution for extreme performance B-Series engines.

These billet runners are CNC-machined from high-grade aluminum and feature a tapered high-velocity design that optimizes airflow into the cylinder head for improved high-RPM efficiency. The trumpet-style runner entries are engineered to reduce airflow turbulence while increasing overall volumetric efficiency.

This configuration supports a single top-mounted 8-injector fuel rail system, allowing for precise fuel delivery in high-boost or high-compression builds. The included billet fuel rail, water fittings, and mounting hardware make this a complete high-performance runner solution for custom race manifold setups.
