Skunk2 B-series GSR pro series intake manifold

Skunk2’s Pro Series Intake Manifold for Honda’s B-series VTEC engines (GS-R only) features a larger plenum and oversized runners when compared to the ITR manifold for maximum horsepower and torque gains. Instead of producing a manifold with a significantly oversized plenum and excessively short runners that would sacrifice mid-range power, the Pro Series manifold was designed for the “street enthusiast” who wants more power but doesn’t want to sacrifice mid-range performance to get it. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.

Ideal for turbocharged and naturally aspirated applications.
Eliminated secondary butterflies for improved airflow and horsepower.
64mm throttle body opening can be port-matched up to 75mm
