Pro Series Intake Manifold for Honda B-Series VTEC

The Skunk2 Pro Series Intake Manifold is engineered to enhance airflow and power output for Honda B-series VTEC engines, specifically the GS-R models. Drawing inspiration from the popular Integra Type R manifold, Skunk2's design incorporates a larger plenum and oversized runners to achieve maximum horsepower and torque gains. The Pro Series manifold provides improved airflow and an enhanced venturi effect, resulting in noticeable power gains across both the mid-range and top-end of the powerband. Its specially tapered runners and larger, tapered plenum work together to preserve mid-range power while accelerating airflow for significant top-end gains. Constructed from shell-molded 356-aluminum and CNC-machined for superior strength and a precise fit, the Pro Series Intake Manifold is a direct-fit replacement for B-series engines. It utilizes three separate flange designs and is compatible with all factory sensors and throttle bodies up to 75mm. The runner exits are machined to precisely match the cylinder head's ports, and the overall design enhances wave scavenging effects at the engine's ideal operating range for a broad increase in usable power. Skunk2 has over a decade of experience in designing, testing, and building intake manifolds. This Pro Series Intake Manifold is vacuum-tested for quality and offers horsepower and torque gains superior to many competitors' manifolds without compromising essential mid-range power.
