Pro Series Intake Manifold for Honda B-Series Engines

The Skunk2 Pro Series Intake Manifold is engineered as a direct-fit replacement for Honda B-series engines, drawing inspiration from the Integra Type R manifold but with significant enhancements. This intake manifold improves airflow and the venturi effect, leading to gains in both mid-range and top-end power. Constructed from shell-molded 356-aluminum and CNC-machined for superior strength and a precise fit, the Pro Series manifold is vacuum-tested for quality. It is compatible with all factory sensors and throttle bodies up to 75mm. The design incorporates specially tapered runners and a larger, tapered plenum to increase and accelerate airflow for significant top-end power gains, while runner exits are machined to match cylinder head ports. The manifold's shape and design also enhance wave scavenging effects for a broad increase in usable power. This manifold is designed for 1990-2001 Acura Integra models (GS, LS, RS, Special Edition) and various other B-series engines. While it is a direct-fit for B-series engines with its three separate flange designs, some installations may require additional components. For example, a water bypass may be needed for certain applications. Additionally, users should be aware that the stock IAT sensor may not fit directly into the Skunk2 manifold, and provisions for its installation point may need to be covered.
