Product Description

The Skunk2 307-05-0280 Pro Series Intake Manifold is engineered for Honda B-series non-VTEC engines, specifically the B18A/B and B20B/Z. Drawing inspiration from the Integra Type R manifold, this intake features a larger plenum and oversized runners to maximize horsepower and torque gains. Unlike manifolds with excessively short runners that compromise mid-range power, the Pro Series is designed to enhance airflow while maintaining strong mid-range performance.

Constructed from 356-aluminum using shell-molding and CNC-machining processes, the manifold ensures superior strength and a precise fit. It's compatible with all factory sensors and throttle bodies up to 75mm, making it a direct-fit replacement for all B-series engines. The design incorporates specially tapered runners and a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains.

Ideal for street enthusiasts, the Skunk2 Pro Series Intake Manifold delivers improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains. It's vacuum-tested for quality assurance and carries a CARB EO Number D-537-2, making it 50-state emissions legal.
