Skunk2’s cast-aluminum Pro Series Intake Manifolds for Honda’s D-series engines are a direct-fit replacement for D-series SOHC VTEC engines and are compatible with all factory sensors and throttle bodies as large as 75mm.

Pro Series Intake Manifolds offer horsepower and torque gains greater than competitors’ manifolds but without compromising mid-range power output. The design incorporates specially tapered runners as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains. Pro Series Intake Manifold runner exits are also machined to best match the cylinder head’s ports. Skunk2’s Pro Series Intake Manifold’s shape and design also increases wave scavenging effects at the engine’s ideal operating range, which allow for a broad increase in usable power.
