Description

Skunk2 Racing is proud to announce the next generation of high performance intake manifolds for the ’02-’05 Civic Si and ’02-’06 RSX/ RSX Type S, and/ or any swap using the K20A/ K20A2/ K20Z1/ K24A1 engines or cylinder heads has finally arrived!

The much anticipated Ultra Race Intake Manifold is the result of years worth of R&D and building upon the performance legacy of our Pro Series Intake Manifold. Using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. The result is a design that is less restrictive, yielding both torque and power gains well over many of the competitors.

 

The K Series Ultra “Street” Manifold uses the EARLY PRB/ PRC style cylinder head and throttle body mounting flange pattern but can be installed on the LATE RBC/ RBB style cylinder heads through the use of an aftermarket Water Bypass Adapter and associated throttle body or throttle body adapter.

RACE APPLICATIONS ONLY – NOT INTENDED FOR STREET USE

3.5 Liter > High Horsepower N/A and Forced Induction Applications to 600HP
4.5 Liter > 600-1000HP
5.5 Liter > 1,000HP Up

Skunk2’s cast-aluminum Pro Series Intake Manifolds for Honda’s D-series engines are a direct-fit replacement for most D-series engines and are compatible with all factory sensors. 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’s Evo Pro Series Intake Manifold in its signature Black Series finish was designed with “street enthusiasts” who utilize turbochargers as small as the factory unit in mind and want more power without sacrificing mid-range performance. Skunk2’s all-new, cast-aluminum Evo Pro Series Intake Manifold—which was tested and developed on the company’s own Evo Time Attack race car—is a direct-fit replacement and offers significant horsepower and torque gains without compromising mid-range power output. Conventional large-plenum, short-runner intake manifolds provide top-end power gains but suffer in the mid-range. Not Skunk2’s. Its all-new Pro Series Intake Manifold features OEM-length runners with larger bores and 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 gains. Peak gains as high as 33+ whp have been realized when paired with Pro Series Throttle Bodies with positive results across the board, beginning as low as 3,200 rpm. Pro Series Intake Manifolds also feature thicker castings when compared to the OEM piece, which leaves plenty of room for porting, and each runner exit is machined and hand-finished to best match the cylinder head’s ports. The Pro Series Intake Manifold’s unique design increases wave scavenging effects at the engine’s ideal operating range, which allow for a broad increase in usable power. Skunk2’s Evo Pro Series Intake Manifold is a simple bolt-on affair. Unlike other intake manifolds, Skunk2’s incorporates the factory configuration, leaving the throttle body in its original location, which means the original intercooler piping and hoses can be reused. Pro Series Intake Manifolds also include the necessary provisions for the Evo’s brake booster line, MDP sensor, and vacuum accessories (EGR valve excluded), and incorporate two additional 1/8-inch NPT threaded ports, which can be used for any number of vacuum/boost-related devices such as gauges, boost controllers, and more.Each manifold comes equipped with plugs and fittings as well as a dipstick k relocator. 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.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 in our signature Black Series finish 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.
