Reduce engine oil temperatures, extend engine life, and keep your horsepower consistent with a PERRIN Oil Cooler.
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.
Each oil cooler kit includes a PERRIN Oil Spacer to allow for easy installation of the thermostat-filter assembly.
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°C at 7000 RPM.
