Extreme increases in oil temperature can break down the oil and decreases its ability to lubricate, cool and clean the engine and can cause damage as a result. HKS Oil Cooler Kits are designed with advanced cooling technology which enables stable oil temperatures to extract the maximum ability from the engine. HKS Oil Cooler R Type can relocate the location of an oil filter so the oil filter replacement can be easily done. As remarkable difference from the others, thermostat is activated by temperature of the oil flow out of the engine, that allows engine oil to be maintained at the ideal temperature. This thermostat has high response and relief feature which activates when differential pressure exceeds 200kPa (2.0kgf/cm2).
Thermostat Opening Temperature 70?
Thermostat Full Open Temperature 80?
The thermostat will bypass the core to maintain the correct oil pressure
