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

ach PERRIN oil cooler uses a Perrin core which maximizes heat dissipation without pressure build-up. This bar and plate design is much stronger than the old style, resulting in a much more durable and efficient core.

 

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. In addition to the OEM oil filter from Subaru, we include a PERRIN spacer which allows for easier installation of the thermostat-filter assembly and increased clearance for the hoses over the headers. 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!
