Skunk2 Racing Pro Series Intake Manifold for Honda/Acura B-series Engines with 70mm Throttle Body Opening

More than a decade ago, Skunk2's engineers looked to the popular Integra Type R intake manifold for inspiration and went back to the drawing board. Skunk2's Pro Series Intake Manifold for Hondas 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. Skunk2's cast-aluminum Pro Series Intake Manifolds for Honda's B-series engines are a direct-fit replacement for all B-series engines thanks to three separate flange designs and are compatible with all factory sensors and throttle bodies as large as 75mm. Pro Series Intake Manifolds offer horsepower and torque gains greater than competitors' manifolds but without compromising mid-range power output. The design incorporates specially tapered runners as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains. Pro Series Intake Manifold runner exits are also machined to best match the cylinder head's ports. Skunk2's Pro Series Intake Manifold's shape and design also increases wave scavenging effects at the engine's ideal operating range, which allow for a broad increase in usable power. Skunk2 is a familiar name in the intake manifold business, with more than 10 years of experience designing, testing, and building them. Similar to OEM manifolds, Skunk2's Pro Series Intake Manifolds are shell-molded from 356-aluminum, CNC-machined for superior strength, a precise fit, and a high-quality finish, and vacuum-tested for quality.

Designed for street enthusiasts seeking increased power without sacrificing mid-range performance, the Skunk2 Racing Pro Series Intake Manifold for Honda and Acura B-series engines offers significant airflow improvements and torque gains. Inspired by the popular Integra Type R intake design, this manifold features a larger plenum and oversized runners, carefully engineered to optimize both top-end horsepower and mid-range torque. The result is a balanced power band that enhances overall engine performance across a broad RPM range, making it ideal for both daily driving and spirited street use.

Constructed from durable 356-aluminum castings and CNC-machined for precise fitment, the Pro Series manifold ensures a high-quality finish and superior strength. Its design incorporates tapered runners and a larger, tapered plenum that promote efficient airflow and wave scavenging effects at the engine's optimal operating range. Compatibility with factory sensors and throttle bodies up to 75mm ensures seamless integration into your existing setup. The manifold’s runner exits are machined to match the cylinder head ports, further improving airflow and performance.

This intake manifold is a direct-fit replacement for all B-series engines, including models from 1997 to 2001 Acura Integra and Honda B18A/B and B20 engines. It features a 70mm throttle body opening that can be port-matched to 74mm for enhanced airflow capacity. The design maintains a focus on mid-range power while increasing airflow for top-end gains, making it an excellent choice for those looking to maximize engine potential without sacrificing daily drivability. Backed by over a decade of engineering expertise, the Skunk2 Pro Series Intake Manifold is a reliable upgrade for enthusiasts aiming for improved horsepower and torque with a professional-grade finish.
