Mishimoto 02-05 Subaru WRX/STi Thermostatic Oil Cooler Kit

Whether you drive a rally-inspired WRX or a finely-tuned STI, maintaining optimal oil temperatures is paramount for both peak performance and long-term engine health. Mishimoto offers a direct-fit oil cooler kit with a built-in thermostat, specifically designed for the 2002-2005 Subaru WRX and STI, ensuring your flat-four engine receives the reliability it deserves.

Advanced Cooling & Control:

  • Thermostatic Sandwich Plate: Features a rear-mounted thermostat that regulates oil flow, ensuring faster engine warm-up and preventing over-cooling during colder conditions.
  • Significant Temperature Reduction: Effectively lowers oil temperatures by more than 20 degrees Fahrenheit under load.
  • Increased Oil Capacity: Adds 0.5 quarts of oil, providing a greater thermal buffer and improved lubrication.
  • Minimal Pressure Loss: Engineered for efficient oil circulation with negligible impact on oil pressure.
  • Application-Specific Design: Includes precision-engineered mounting brackets and pre-made stainless steel braided oil lines for a perfect fit.
  • High-Efficiency Cooler: Utilizes a 10-row stacked-plate Mishimoto oil cooler for maximum heat dissipation.

This kit is ideal for enthusiasts who demand consistent performance and enhanced durability from their Subaru WRX or STI. The integrated thermostat provides an added layer of protection, making it suitable for daily driving and aggressive track use. Protect your investment and unlock your Subaru's full potential.
