HKS Racing Suction Intake for Evo 4

The HKS Racing Suction Intake System for the Evo 4 increases horsepower by letting your car breath. With this HKS Intake system, you'll notice a more audible intake noise, as well as a small WOOSH from your factory blow off valve.

Includes all necessary hardware, brackets, couplers, and hoses to bolt on to an otherwise factory Evo 4 without any modification necessary.
