Pro Series Intake Manifold for Honda B-Series Non-VTEC

The Skunk2 Pro Series Intake Manifold is a direct-fit replacement cast-aluminum manifold engineered for Honda B-series non-VTEC engines. This manifold is crafted to enhance airflow and the venturi effect, resulting in significant improvements in both mid-range and top-end power. The design incorporates specially tapered runners and a larger, tapered plenum which work together to preserve mid-range power while accelerating airflow for substantial top-end gains. The runner exits are precisely machined to best match the cylinder head's ports, further optimizing flow. Constructed from 356-aluminum using a shell-mold process and then CNC-machined for superior strength and fit, this intake manifold is vacuum-tested for quality. It is designed to be compatible with all factory sensors and throttle bodies up to 75mm, and utilizes three separate flange designs for broad B-series engine compatibility. However, it is noted as not compatible with 1990-1993 engines featuring an EGR valve. This Pro Series Intake Manifold is intended for the 'street enthusiast' seeking increased power without sacrificing crucial mid-range performance. Its design also enhances wave scavenging effects at the engine's ideal operating range, contributing to a broader increase in usable power across the RPM band. The manifold is CARB Exempt.
