2015-2019 WRX Oil Cooler Kit by Perrin

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

Each PERRIN oil cooler uses a Setrab core which maximizes heat dissipation without pressure build-up. Oil-ways are interspaced with airway corrugations providing optimum heat transfer, while the oil passages use "turbulators" to break down boundary layer effects in the oil flow

The PERRIN Performance filter adapter features an integrated 85°C (185°F) thermostat. This means oil will not start flowing through the oil cooler until oil temps reach an optimum temperature of 85°C

PERRIN's STI/WRX 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
