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 Hondas B-series VTEC engines (GS-R only) features a larger plenum and oversized runners when compared to the ITR manifold for maximum horsepower and torque gains.
I received the B18C1 Skunk2 Pro Series Intake Manifold earlier than expected. Everything looks good so far. Fitting look intact, item number matches the description, and there is no obvious physical damage. Thanks for getting the item out in a timely fashion. Keep up the hustle.
