Perrin Oil Cooler Kit 2002-2014 WRX / 2004-2021 STI

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

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 7,000 RPM.

• High-Efficiency Core: This bar and plate style oil cooler core maximizes heat dissipation without restricting oil flow to ensure your engine is fed with full oil pressure. 
• 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: Allows for easy installation of the thermostat-filter assembly.
• 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.
• Mounting Brackets: Easily allow the oil cooler core to mount directly to existing holes in the OEM core support of your vehicle. Made from 304 Stainless steel, the brackets look sleek and stylish while blending seamlessly behind your bumper.
