An intercooler is an air-to-air radiator, taking heat -- which is the natural result when you compress a gas -- and transferring it from the intake charge to the outside world. Keeping the intake charge cool is the intercooler's job, and generally speaking, the larger the intercooler, the cooler your intake temperatures will be. Mach V Motorsports carries a wide selection of Subaru intercoolers and intercooler piping kits for sale from Cobb Tuning, Perrin, Mishimoto, GrimmSpeed, AVO, Process West, and TurboXS. In this section you'll also find intercooler splitters and Killer B oil fill relocation tubes.
