Perrin Thermostatic Oil Cooler Kit Black 2022-2023 WRX

Each PERRIN oil cooler uses a Perrin designed 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. The turbulators are fully brazed to the entire internal length of the tube resulting in zero heat transfer barrier and high strength.

Why You Want This

In racing conditions engine oil temperature skyrockets. This causes decreased engine performance and reduces the oil's ability to properly lubricate. A well-designed engine oil cooling system like the PERRIN Oil Cooler Kit will help keep temperatures within the desired temperature range, thus maintaining performance and prolonging engine life. Most setups can see a drop of approximately 15°-20°F up to redline.

Heat Exchanger

Using a bar and plate core maximizes heat dissipation without pressure build-up. Oil-ways are interspaced with in-line turbulators 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 low pressure lost.

Integrated Thermostat

The PERRIN Filter Adapter features an integrated 85°C (185°F) thermostat. This means your oil will reach the optimum operating temperature of 85°C within the engine before it is released to the oil cooler.

Oil Spacer

In addition to a new OEM oil filter from Subaru, we include a PERRIN Oil Spacer to allow for easy installation of the thermostat-filter assembly.
Mounting Brackets

Preassembled Hoses

The PERRIN Oil Cooler Kit features lightweight Aeroquip brand -10 hose that are rated for 250psi and 300°F continuous temperature. Each hose comes pre-assembled and wrapped with our Industrial grade Pyrojacket that can withstand continuous exposure to 500° F (260°C) and up to 2000°F (1090°C) for 15-20 minutes.

The PERRIN Oil Cooler comes with custom brackets that allow the oil cooler core to mount directly to existing holes in the OEM core support of your vehicle. Made from CNC machined 6061 T6 aluminum, the brackets look sleek and stylish while blending seamlessly behind your bumper.
