Skunk2’s Pro Series Intake Manifold for Honda’s K-series has arrived. Skunk2 engineers looked to the popular ’06+ Civic Si’s RBC intake manifold for inspiration and went back to the drawing board. Skunk2’s Pro Series Intake Manifold for Honda’s K-series features a larger plenum and shorter, oversized runners when compared to the RBC, and is 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, 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 all-new, cast-aluminum Pro Series Intake Manifold for Honda’s K-series is a direct-fit replacement for all K20/K24 engines thanks to its unique, patent-pending water neck design and throttle body flange, which is compatible with OEM throttle bodies as well as those as large as 76mm (’06+ Civic Si requires adapter, sold separately). The special water neck design eliminates the cutting that would otherwise be involved with some RBC applications (remaining applications require special 1.0 x 11.5-inch NPT plug, sold separately), 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 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.

Notes:

Skunk2’s all-new Pro Series Intake Manifold for Honda’s K-series is compatible with all K20/K24 engines. Its unique design allows for a bolt-on fit without any cutting, drilling, or special adapters.

Pro Series Intake Manifolds feature an angled design for clearance on all ’88-’00 Civics and ’90-’01 Integras with K-series engine swaps.

All Pro Series Intake Manifolds are shell-molded and CNC-machined for superior strength, a precise fit, and a high-quality finish. Each manifold also includes a Skunk2 nameplate for authenticity.

Pro Series Intake Manifolds feature larger plenums and shorter, oversized runners when compared to Honda’s ’06+ Civic Si (RBC) manifold, and are cast with thicker wall material.

Throttle bodies as large as 76mm can be bolted up to K-series Pro Series Intake Manifolds without the need for adapters.

Each runner exit is machined and hand-finished to best match the cylinder head’s ports.

The special water neck design eliminates the cutting that would otherwise be involved with some RBC applications (remaining applications require special 1×11.5-inch NPT plug, sold separately).

Skunk2 Pro Series Intake Manifolds are computer-designed and tested to ensure improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.

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 with specially shaped, tapered plenums and runners that maximize top-end gains but not at the expense of mid-range power.

Pro Series manifolds are cast with thicker wall material, leaving room for further porting for high-horsepower applications.

Skunk2’s unique runner shape and angle allow for additional hood clearance for most K-swapped Civics and Integras.

Skunk2 engineers use CFD (computational fluid dynamics)—the branch of fluid mechanics that uses numerical methods and algorithms to analyze and solve fluid-flow problems—to perform the millions of calculations required to simulate fluid and gas interactions within complex surfaces such as intake manifolds.
