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 manifolds significantly increase horsepower between 3000-8800 rpm; the broadest powerband increase in the industry. Our new Pro-Series design features a 22% increase in power over our previous design. Engineered with a larger plenum and tapered runners, Skunk2 manifolds increase and accelerate airflow, and are designed to increase the effects of wave scavenging at the engine’s optimum operating RPM range providing a broad overall increase in usable power. Each runner entry is also modified to balance airflow between cylinders. Oversized throttle bodies can be used as a result of the modified IAC opening on the flange.
