Perrin 02-14 WRX / 04-21 STI Oil Cooler Kit | PSP-OIL-110
Reduce engine oil temperatures, extend engine life, and keep your horsepower consistent with a PERRIN Oil Cooler.
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 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
The PERRIN Oil Cooler comes with custom brackets that allow the oil cooler to mount easily to the front of your vehicle. Made with 304SS to ensure the brackets last the life of the car.
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.
