The Skunk2 Pro Series Intake Manifold for Honda D-Series engines is a high-flow, performance-engineered replacement for the restrictive OEM manifold, designed to maximize mid-to-top-end horsepower and torque. Ideal for both naturally aspirated and turbocharged applications, it provides a significant airflow upgrade for performance-minded builds.

Precision cast from aircraft-grade A356 aluminum, the Pro Series manifold features an oversized plenum and long, tapered runners that enhance volumetric efficiency and deliver a stronger venturi effect for increased power across the rev range. Each unit is vacuum tested to ensure leak-free performance, then finished in a durable black wrinkle powder coat for a race-ready appearance.

Designed for direct bolt-on fitment, this manifold retains compatibility with OEM sensors while offering a 66mm throttle body opening that can be port-matched up to 70mm for higher-flow setups. For engines producing up to 400 bhp (turbo) or 200 bhp (NA), this intake manifold unlocks the breathing potential your D-series engine needs to perform.
