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 Intake Manifold Install K20z3. Skunk2 Pro-Series Intake Manifold: Skunk2 Racing's Pro-Series Intake Manifold improves airflow thus increasing horsepower by as much as 8% over stock manifolds on stock engines and even more on modified or forced-induction engines. Skunk2 Pro-Series Intake Manifold for the 06-11 8th generation Honda Civic Si. This is one of the top Intake Manifolds you can put onto your k20 Honda Civic Si. The increased airflow provides more hp from low to high rpm, but the overall improved efficiencies gives you an 8% boost on average on a stock motor.

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.

Honda’s RBC intake manifold is popular for a reason. It’s a relatively simple and inexpensive bolt-on that yields impressive power gains. It's well optimized for relatively stock K-series engines, which means improving upon it isn’t easy. Como desinstalar plugins photoshop. So when Skunk2 released its Pro Series Intake Manifold for K-series engines, the speculation as to whether or not it would outperform Honda’s RBC wasn’t surprising. Skunk2's goal was to design a manifold that would perform well on highly modified engines as well as stock ones. Although the RBC manifold performs well on relatively mild engines, once compression ratios, displacement, and cam timing are increased, its performance is extremely limited. Fortunately, the dyno doesn’t lie, and Skunk2 is happy to present the definitive results of nearly a year’s worth of testing.

Skunk2’s Pro Series Intake Manifold for Honda’s K-series engines has arrived. Similar to Skunk2's already popular K-series Intake Manifolds, Skunk2's engineers looked to the popular '06-'11 Civic Si’s RBC intake manifold for inspiration and went back to the drawing board. 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.
