2002-2015 Subaru Impreza WRX STI* Perrin Performance Oil Cooler Kit PSP-OIL-100

More details

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. Setrab Oil Coolers employ an in-line turbulator to gently stir the fluid  being cooled, thereby ensuring that the fluid has exposure to the  entire internal surface area of the oil cooler with the least pressure  lost. The turbulators are fully brazed to the entire internal length of  the tube resulting in zero heat transfer barrier and high strength.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.The PERRIN Oil Cooler comes with custom brackets that allow the oil  cooler core to mount directly to existing holes in the OEM core support  of your vehicle. Made from CNC machined 6061 T6 aluminum, the brackets  look sleek and stylish while blending seamlessly behind your bumper.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!PERRIN Performance warrants to the original purchaser that all  PERRIN products will be free from defects in material and workmanship  within a sixty (60) month period from the date of purchase. *Some  exclusions apply
