The Skunk2 Ultra Series Race Intake Manifold is engineered for high-horsepower builds, utilizing Computational Fluid Dynamics (CFD) to optimize airflow and distribution. This three-piece modular design features a removable plenum, allowing for easy porting and volume adjustments via optional plenum spacers. The manifold is constructed with generously cast runner walls to provide ample material for custom porting, ensuring it can grow with your engine's performance needs.

Each manifold features 6.5-inch tilted and tapered high-velocity runners paired with 87mm raised velocity stacks. The 90mm throttle body flange utilizes the standard 5.0L Ford pattern for broad compatibility with aftermarket throttle bodies. For high-fuel demand applications, the runners include provisions for additional injectors on the underside.
