Skunk2 Racing Pro-Series Intake Manifold is your best bet if increasing horsepower is the main objective. It improves airflow, which increases the horsepower by up to 8% over stock manifolds on stock engines. Its performance is even better in case of modified or forced-induction engines. Skunk2 Racing Pro-Series Intake Manifold has revolutionized the manifolds engineering with significant horsepower increase between 3000-8800 rpm, which is the broadest power-band increase in the industry. The all-new Skunk Pro-Series is a marked improvement over its previous versions. With accelerated airflow and peculiar design, which increases the effects of wave scavenging at the engine’s optimum operating RPM range, the Skunk2 Racing Pro-Series Intake Manifold manages 22% increase in power over its predecessors. Each runner entry is also modified to balance airflow between cylinders. Skunk2 manifolds have modified IAC opening on the flange, which allows the use of oversized throttle bodies. Skunk2 manifolds are shell-molded and CNC-machined, which gives them superior strength, high-quality finish, and a precise fit. To ensure highest standards and safety, each manifold is vacuum tested. Skunk2 Racing Pro-Series Intake Manifold is ideal for NA and forced induction, and uses all stock sensors and auxiliaries for a simple bolt-on installation for maximum power.
