Skunk2 Cast Intake Manifold (Black) for Evo 7/8/9 (307-06-0505) Skunk2

The Skunk2 manifold is a great piece as-is, but coupled with a custom STM porting process, we are able to really open it up and access all its potential! We could hammer you with charts and flow graphs… but we will make it easy: This is the manifold we used on the STM RS, and it held the top spot for the Quickest and Fastest CT9A on Earth for three years with an 8.0@182. It’s got terrific drivability and proven potential.

Vehicle Fitment:
2001-2006 Evolution VII VIII IX

Options:
• Standard in the Box
• STM Custom Race Porting (+$300)

Finish:
• Black Powdercoat

The intake manifold solution street-driven Evo VII-IX owners have been waiting for is here. Skunk2’s Evo Pro Series Intake Manifold 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 has been tested and developed on the company’s own Evo Time Attack race car. It 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 Skunk 2’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. 

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 ports, which can be used for any number of vacuum/boost-related devices such as gauges, boost controllers, and more.

Skunk2 is a familiar name in the intake manifold business, with more than 10 years of experience designing, testing, and building manifolds for the Honda market. Similar to OEM manifolds, Skunk2’s Pro Series Intake Manifolds are shell-molded and CNC-machined for superior strength, a precise fit, and a high quality finish. 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.
