More than a decade ago, Skunk2’s engineers looked to the popular Integra Type R intake manifold for inspiration and went back to the drawing board. Skunk2’s Pro Series Intake Manifold for Honda's B-series engines features a larger plenum and oversized runners compared to the ITR manifold, delivering maximum horsepower and torque gains. Instead of producing a manifold with an excessively oversized plenum and short runners that would compromise mid-range power, the Pro Series manifold was designed for street enthusiasts who want more power without sacrificing mid-range performance. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.

Skunk2’s cast-aluminum Pro Series Intake Manifolds for Honda’s B-series engines are available in silver or black and fit B16, B17, B18, and B20 engines, accommodating both VTEC and non-VTEC heads. These manifolds are a direct-fit replacement for all B-series engines thanks to three separate flange designs and are compatible with all factory sensors and throttle bodies as large as 75mm, making them suitable for both turbocharged and naturally aspirated builds. The design features specially tapered runners and a larger, tapered plenum that significantly increase and accelerate airflow, leading to notable top-end power gains. Additionally, the runner exits are precisely machined to match the cylinder head’s ports, ensuring optimal performance. The manifold supports throttle bodies as large as 75mm, making it a versatile upgrade for various setups.
