ContentSkunk2's engineers looked to the popular '06-'10 Civic Si’s RBC intake manifold for inspiration when developing our Pro Series Intake Manifold 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 and we are happy to say they have finally arrived! 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 K-series engines (excluding '06-'10 Civic Si) thanks to their unique, patent-pending water neck designs and throttle body flanges, which are compatible with OEM throttle bodies as well as those as large as 76mm. The special water neck designs eliminate the cutting that would otherwise be involved with some RBC applications and the supplied thermal-insulated intake manifold gasket makes 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 ’88-’00 Civics and ’90-’01 Integras with K-series engine swaps, as well as additional core support clearance on ’02-’05 Civic Sis. 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. 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 its signature Black Series finish for Honda's B-series VTEC engines (non-GS-R) 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.

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.    The intake manifold solution street-driven Evo VIII-IX owners have been waiting for is here. Skunk2’s newly designed 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—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’s Pro Series Intake Manifold for most Honda SOHC D-series engines features a larger plenum and oversized runners when compared to the OEM version 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.
