Each PERRIN oil cooler uses a Setrab core. This core maximizes heat dissipation without pressure build - up. The oil - ways and airway corrugations work together for optimum heat transfer, and the 'turbulators' in the oil passages break down boundary layer effects in the oil flow. Setrab Oil Coolers use an in - line turbulator to stir the fluid, ensuring full exposure to the internal surface area of the oil cooler with minimal pressure loss. The turbulators are fully brazed to the tube for zero heat transfer barrier and high strength. The PERRIN Performance filter adapter has an integrated 85°C (185°F) thermostat. Oil won't flow through the cooler until it reaches 85°C. Along with the OEM oil filter from Subaru, a PERRIN spacer is included for easier installation of the thermostat - filter assembly and more clearance for the hoses over the headers. PERRIN's WRX oil cooler kit uses lightweight Aeroquip brand - 10 hose rated for 250psi and 300°F continuous temperature. The anodized - 10 push - lock type aluminum hose ends don't need clamps, but PERRIN adds them for extra security. And unlike other kits, the hoses are pre - assembled for you!
Using this Perrin oil cooler kit is straightforward. First, make sure you have the right Subaru part number 21328AA140 if your car is a 2002 - 2007 WRX or 2004 - 2007 STI. Then, follow the installation guide provided, which should take about 2 hours. When it comes to adding oil, remember you'll need an additional 1 quart. During use, the oil won't start flowing through the cooler until it reaches 85°C, thanks to the integrated thermostat. This helps keep your engine running at an optimal temperature. For maintenance, regularly check the hoses and fittings to make sure there are no signs of leaks or damage. The hoses are built to last, rated for 250psi and 300°F continuous temperature, but it's always good to double - check. Also, keep an eye on the oil level and change the oil as recommended by your car's manufacturer. With a 5 - year manufacturer warranty, you can have peace of mind knowing that you're covered if anything goes wrong.
