Skunk2 Honda Civic Si (02–05), Acura RSX/RSX Type S (02–06), Honda K20A, K20A2, K20Z1 And K24A1 Applications - Ultra Race Intake Manifold - K20A2 Style - All Black

Skunk2 Racing is proud to announce the next generation of high performance intake manifolds for the '02-'05 Civic Si and '02-'06 RSX/ RSX Type S, and/ or any swap using the K20A/ K20A2/ K20Z1/ K24A1 engines or cylinder heads has finally arrived! The much anticipated Ultra Race Intake Manifold is the result of years worth of R&D and building upon the performance legacy of our Pro Series Intake Manifold.

Using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a three-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum and optional plenum spacers. The result is a design that is less restrictive, yielding both torque and power gains well over many of the competitors. Fits MOST Popular Chassis Configurations - Not Just Race Cars - See Notes
