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 VTEC engines (GS-R only) 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.

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Intake manifolds direct the airflow from the air intake into your vehicle's cylinder head. An aftermarket intake manifold can increase the airflow and horsepower of your engine.

All Skunk2 products are carefully planned and designed in-house using the latest computer simulation and modeling techniques, followed by careful testing in controlled laboratory environments using state-of-the-art equipment. Each product is then subjected to rigorous dyno, street, and race track testing to ensure proper performance in the most extreme conditions. For these reasons, top street cars and race cars worldwide rely on Skunk2 products. As part of Skunk2’s commitment to developing industry-leading products, we’ve remained actively involved in various forms of motorsports through technical partnerships, sponsorships, as well as with our own race vehicles for more than 15 years. We’ve gone on to secure a number of drag racing and road racing records and championships, including earning the title of the world’s first 10-second naturally aspirated Honda. Racing provides us with the data necessary to produce high-performance parts utilizing innovative designs, advanced metal alloys, cutting-edge manufacturing methods, and stringent quality-control measures. Driven by the desire to make things go faster, Skunk2’s staff is comprised of industry leaders, racers, and enthusiasts who are passionate about what they do and understand what other enthusiasts want. Our perspective is shaped by real-world racing experiences as well as by practical science, and that's precisely what makes Skunk2 products so good. Firmly grounded in our understanding of engineering, we make every effort to embrace advanced technology. Our goal is to make performance and technology accessible to other enthusiasts through innovative manufacturing techniques. Since 1994, we’ve released a number of industry-leading products, including the first cast aluminum, high-performance intake manifold, cutting-edge composite fuel rails, and valvetrain components made from premium materials. Skunk2 is acclaimed as being the first U.S.-based sport compact parts manufacturer to offer CNC-machined, adjustable cam gears in 1995 as well as billet camshafts in 1999. As a result of continually pushing our engine development capabilities in the racing world, we’ve discovered a number of exciting “power secrets” that are incorporated into every Skunk2 product. Today we continue our tradition of creating leading-edge products through a state-of-the-art engineering and R&D department as well as through extensive engine development and testing both on the race track and the street.
