HKS S-Type Oil Cooler Kit - 08-14 Subaru Impreza STI

HKS oil cooler kits are a great way to keep your engine running strong for a long time. Constructed of 100 percent aluminum, these kits keep oil temps down by circulating hot oil from inside the engine through the cooler and back. Available in a variety of applications, HKS is sure to have you covered.

HKS Oil Coolers use high performance cooling cores and so there is the possibility of overcooling which is prevented with the use of a thermostat (some vehicles excluded). This thermostat has high response and so is able to react quickly to changing oil temperatures. Once oil temperature reach the set levels, the oil will flow through the cooler core but bypass it when temperatures drop below. This allows engine oil to be maintained at the ideal temperature.
- Thermostat Opening Temperature 70C (+/-3C)
