Perrin Thermostatic Oil Cooler Kit

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

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 at 7000 RPM.

Bar And Plate Core

Each PERRIN oil cooler uses a high-efficiency PERRIN bar and plate-style oil cooler core. This core design maximizes heat dissipation without restricting oil flow to ensure your engine is fed with full oil pressure. This bar and plate design is much stronger and withstands damage from normal road debris more efficiently than tube and fin type cores. The mounting holes and hose connection points are also more durable.

Integrated Thermostat

The PERRIN Filter Adapter features an integrated 85°C (185°F) thermostat. This means your oil will reach its optimum temperature of 85°C much faster.

In addition to the OEM oil filter from Subaru, we include a PERRIN spacer which allows for easier installation of the thermostat-filter assembly.

Mounting Brackets

The PERRIN Oil Cooler comes with custom brackets that allow the oil cooler core to mount easily to the front of your vehicle. Made with 304SS to ensure the brackets last the life of the car.

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.

Preassembled Hoses

The PERRIN Oil Cooler kit uses lightweight Aeroquip brand -10 hose that is rated for 250psi and 300°F continuous temperature. Each hose consists of anodized -10 push-lock type aluminum hose ends. These fittings are designed to fit without the need for clamps, but we take the extra step and add a clamp ensuring they will never come apart. Unlike other kits that make you assemble your hoses, PERRIN preassembles them for you!

PERRIN's hoses are made using Industrial grade Pyrojacket. Pyrojacket withstand continuous exposure to 500° F (260°C); up to 2000°F (1090°C) for 15-20 minutes; and up to 3000°F (1650°C) for 15-30 seconds. When exposed to flame, the silicone rubber transforms into a crust, creating a protective SiO2 refractory layer.
