Skunk2's new Pro-Series design features a 22% increase in power over our previous design. 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.
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.
