Skunk2’s Pro Series Intake Manifold for Honda’s B-series non-VTEC engines 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.
Not compatible with ’90-’93 engines featuring EGR valve; must use reprogrammed or later model ECU.
Not compatible with ’90-’95 throttle bodies featuring fast idle valve; must use Skunk2 throttle body or similar.
64mm throttle body opening can be port-matched up to 75mm.
