Description

The Subaru WRX STI provides a great balance of power, handling, and reliability. As with any vehicle, controlling fluid temperatures will ensure consistent power and engine longevity. The Mishimoto Subaru WRX STI Oil Cooler Kit was developed specifically for the 2015 STI and is a great addition to any street or track-driven vehicle. A large 19-row cooler mounts in the front bumper to provide optimal airflow and cooling efficiency. The included direct-fit mounting brackets and preassembled stainless steel lines with -10AN fittings will ensure an easy and hassle-free installation. This cooler is proven to reduce oil temperatures by 20+ degrees Fahrenheit (16+degrees Celsius) degrees while maintaining minimal pressure loss. For further heat protection, this kit includes thermal reflective wrap for the oil lines, providing substantial heat deflection from the nearby exhaust. The Mishimoto Subaru WRX STI Oil Cooler Kit can be customized to meet your needs with either a Stealth Black or Sleek Silver cooler and your choice of the Mishimoto Oil Sandwich Plate or the Mishimoto Thermostatic Oil Sandwich Plate. As with all our products, this kit includes the Mishimoto Lifetime Warranty.
