MISHIMOTO MMOC-STI-15 SUBARU WRX STI Oil Cooler Kit, 2015+

Description MISHIMOTO MMOC-STI-15 SUBARU WRX STI Oil Cooler Kit, 2015+

The Subaru STI offers a strong combination of power, handling, and reliability. Managing fluid temperatures is essential for consistent performance and engine longevity. The Mishimoto Subaru STI Oil Cooler Kit is designed specifically for the 2015-2021 STI and is suitable for both street and track use.

This kit features a large 19-row Mishimoto cooler mounted in the front bumper for optimal airflow and cooling efficiency. Direct-fit mounting brackets and preassembled stainless steel lines with -10AN fittings allow for straightforward installation. The cooler is proven to reduce oil temperatures by over 20°F (16°C) with minimal pressure loss. Thermal reflective wrap for the oil lines is included to provide additional heat protection from the exhaust. The kit is available with either a Sleek Silver or Stealth Black cooler and a choice of Mishimoto Oil Sandwich Plate or Thermostatic Oil Sandwich Plate.

Installation Notes: Recommended torque specification for all straight fittings and banjo bolts: 15-25 ft-lb. Do not exceed the maximum torque rating of 35 ft-lb.

Caution: It is the installer's responsibility to check all thermostat plugs, NPT plugs, line fittings, and other connections to ensure they are fully tightened before operating the vehicle. Mishimoto recommends checking all connections at regular intervals, especially during the first few miles after installation. For additional technical information, contact the customer experience team.

Note: This oil cooler kit is compatible only with models equipped with a single scroll turbo and un-equal length exhaust manifold. Models with a twin scroll turbo and equal length exhaust manifold may not be compatible.
