$90.00

Fits 2003-2006 Mitsubishi Lancer Evolution VIII/IX and 2008 Evolution X GSR/MR models.

The HKS Low Temperature Oil Cooler Thermostat is an essential upgrade for Mitsubishi Evolution owners who take their vehicles to the track or drive aggressively under high-load conditions. The factory thermostat is designed for general street use, often opening at a higher temperature that can lead to excessive heat soak during spirited driving. This HKS unit features a 75°C opening temperature, allowing oil to flow through the external cooler sooner to maintain more stable operating temperatures and prevent thermal breakdown of the lubricant.

  • Manufacturer Part Number: 15999-AM001
  • Opening Temperature: 75°C (167°F)
  • Optimized for performance driving and track use to manage engine oil heat
  • Direct-fit replacement for the factory oil cooler thermostat
  • Helps maintain consistent oil viscosity and engine protection
