Our latest Type 5 Dual Port BOV made specifically for the 2015 WRX features the innovative new Smart Port drive-by-wire friendly staging technology that gives you the response of a plumb-back valve, with the high performance benefits of a vent-to-atmosphere valve. The Smart Port system involves a new piston manufacturing process utilizing specialized alloys and coatings, along with a revolutionary new vent to atmosphere trumpet design. These new designs allow for very fast response while also providing enhanced sealing. The result is quicker spool-up and better performance on modern drive-by-wire vehicles.

The much anticipated Ultra "Street" intake manifolds for the Honda B16A/ B17A and B18C engine or VTEC cylinder heads has finally arrived!
The Ultra Series is years of research and development, culminated in a multi-piece cast aluminum intake manifold that offers advantages that only a modular design could allow. Using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a two-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum lid and optional plenum spacers. In addition to CFD testing, the Ultra Series Intake Manifold has undergone extensive in-house dyno testing which has led to a design that is less restrictive, yielding both torque and power gains well over many of the competitors.
Skunk2 Racing Ultra Street Intake Manifolds are cast-aluminum, manufactured from high-grade 356 aluminum alloy for strength and lightweight. Each manifold is CNC-machined for a precise fit, and individually inspected for quality assurance. The Ultra Series Street manifold features a generous 74mm throttle body opening and is constructed with thick walls at entry, minimizing concerns of breakthrough when port matching. Intense planning and design went into the plenum to distribute even airflow to all four cylinders under dynamic load conditions. Placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. Large velocity stack raised bell mouth entries lead to 8.72” long intake runners with smooth transitions allowing the Ultra Street Intake Manifold to really move some air!
Skunk2 Racing Ultra Street Intake Manifolds are designed to be used in modified naturally aspirated applications as well as mild turbo/supercharged setups.
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 Honda's 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. Each manifold is molded with smooth transitions from the throttle body opening to the plenum to the runners with clean parting lines for an optimal finish, both inside and out and features a genuine Skunk2 nameplate.
Skunk2 is proud to introduce the 70mm Alpha Series Throttle Body for Honda B16/ B17/ B18/ B20/ D15/ D16/ F20/ F22/ F23/ H22 and H23 engines in its exclusive, fine shot-blasted surface finish. Skunk2’s Alpha Series Throttle Body is designed to be used with Skunk2’s Pro Series Intake Manifolds as well as OEM and other aftermarket intake manifolds for bolt-on horsepower and torque gains by maximizing engine airflow, all at a competitive price.
A larger throttle body is key to producing additional power throughout the powerband on modified engines with increased airflow demands and the Skunk2’s 70mm Alpha Series Throttle Body delivers! Sealed ball bearings, a precision machined throttle plate and a honed oversized bore insures smooth operation on the most aggressive naturally aspirated and forced induction applications.
NOTE: Due to Larger Diameter... You Must Use A Skunk2 Pro Series Intake Manifold or Make Adjustments to Intake Manifold Throttle Body Flange to Match Bore and Keep IAC (Idle Air Control) Passage Separate. Not compatible with B18C GS-R intake manifold. Not compatible with D Series engines featuring down-flow intake manifolds. Manual Transmission Only.
We’ve streamlined the process and revised the design of the K Series Ultra Fuel (350-05-7000) to replace the Ultra Fuel Rails listed below.
The Skunk2 Racing K Fuel Rail is the perfect compliment to the Ultra Street Manifold and especially the Ultra Race Intake Manifold with its dual injector positions. This K-Series Fuel Rail is used for both the primary injector position and the secondary injector position. One rail, two positions.

Skunk2's engineers went back to the drawing board when they set out to improve the already popular '06-'11 Civic Si’s RBC intake manifold. Each of Skunk2’s Pro Series Intake Manifolds for Honda’s K-series engines feature larger plenums and shorter, oversized runners when compared to the RBC, and are cast with thicker wall material, leaving room for further porting for high-horsepower applications. Instead of producing a manifold with a significantly oversized plenum and excessively short runners that would sacrifice mid-range power, Pro Series manifolds were 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 all-new, cast-aluminum Pro Series Intake Manifolds for Honda’s K-series engines are a direct-fit replacement for all '06-'11 Civic Si engines thanks to their unique design and throttle body flanges, which are compatible with OEM throttle bodies as well as those as large as 76mm. A thermal-insulated intake manifold gasket is also included, making for a truly bolt-on installation (no drilling or modifying required). Pro Series manifolds also incorporate an angled-runner design, which allows for ample hood clearance on almost any engine combination. Pro Series Intake Manifolds offer horsepower and torque gains greater than the popular RBC manifold but without compromising mid-range power output. The design incorporates runners that are similar in length to the RBC’s but with larger bores, a special tapered design, 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 and hand-finished 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.
