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. With the more mods, headwork, cams or forced induction this intake manifold will help provide the power and remove the bottleneck of the more restrictive oem unit. Engineered with larger plenum and tapered runners, this skunk2 intake manifold is built to increase airflow, and increase wave scavenging effects to provide a broad power range. Each runner is balanced for optimal and equal airflow into each cylinder. The manifold is also built to accept over-sized throttle bodies without the need for machine porting by the end user. Just like OEM skunk2 manifolds are shell molded and CNC Machined for quality and performance. Each manifold is vacuum tested to ensure proper function when you install.
