Skunk2's Pro Series Intake Manifold has an optimized design for the '02-'05 Civic Si, '02-'06 RSX/RSX Type S, plus K20A/K20A2/K20Z1/K24A1 engine swaps. Enjoy larger plenum & shorter, oversized runners to augment airflow & emphasize the venturi effect. Constructed with thicker material for powerful engines & potential porting, enjoy increased power without need for modifications. This system features a direct-fit & thermal-insulated gasket for leak-proof sealing, plus no-modification-needed installation. Angled runners provide ample clearance for '88-'00 Civics & '90-'01 Integras with K-series swaps. The Pro Series outperforms the RBC manifold with improved HP & torque gains & a wider usable power range. Crafted from 356-aluminum & CNC-machined for precision, polished & vacuum-tested for strength.
