The 2006+ Honda Civic Skunk2 Pro-Series Intake Manifold was created by engineers who took the Si’s popular RBC manifold, and made improvements to increase airflow. The Pro-Series manifold features larger plenums and shorter, oversized runners that are cast with thicker wall material. The thicker wall allows for more room to port for higher horsepower applications. The runner exits are also machined and hand finished to best match the cylinder’s head ports. Pro-Series manifolds have a 70mm throttle body bore, and are compatible with up to 76mm throttle bodies. The Skunk2 Pro-Series is a reputable manifold that increases airflow while giving horsepower gains in both mid-range and top-end.
