PERRIN | Oil Cooler Kit - WRX / STi 2002-2021

OVERVIEW

Reduce engine oil temperatures, extend engine life, and keep your horsepower consistent with a PERRIN Oil Cooler.

Heat Exchanger

Each PERRIN oil cooler uses a Setrab core which maximizes heat dissipation without pressure build-up. Oil-ways are interspaced with airway corrugations providing optimum heat transfer, while the oil passages use "turbulators" to break down boundary layer effects in the oil flow. Setrab Oil Coolers employ an in-line turbulator to gently stir the fluid being cooled, thereby ensuring that the fluid has exposure to the entire internal surface area of the oil cooler with the least pressure lost.
