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.
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.
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.
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.
The PERRIN Oil Cooler comes with custom brackets that allow the oil cooler to mount easily to the front of your vehicle. Made with 304 Stainless Steel to ensure the brackets last the life of the car.
Full PERRIN Oil Cooler Kits feature 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.
PERRIN Oil Cooler Tuner Kits are perfect for custom race applications and/or show car setups where you want to create your own custom hoses and fittings. A PERRIN Oil Cooler Tuner Kit will supply the core and brackets, you supply the rest.
