Features & Product Details

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 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!

  • Q: perrin oil sandwich adapter  cruzcontrol.musubi2 years ago

    can the PERRIN Oil Sandwich Adapter (Part # ASM-GAU-100) replace the sandwich adapter that comes with this kit?
    • 2 of 2 people found the following answer helpful

      A:  You cannot use ASM-GAU-100 alone. You will need to use the Oil cooler adapter that comes with the kit along with ASM-GAU-100.

  • Q: Perrin oil cooler   lsfiridis83860933 years ago

    I want to put in oil and temp gauges, does the sandwich plate have connections for the sensors?
  • Q: FMIC fitment  kechup1473 years ago

    Hey, anyone used this kit with ETS fmic ? Also how would a fmic restrict the air flow to this oil cooler ? any significant difference ? Thanks!
    • 1 of 1 people found the following answer helpful

      A:  We have not used this oil cooler with an ETS FMIC, but they should be compatible. An FMIC may restrict some airflow to the cooler core, but you could re-position the core or leave it behind the FMIC with minor impact on airflow.
