HKS S-Type Oil Cooler 2008-2021 STI
Here, you are looking at the HKS S-Type Oil Cooler for the 2008-2021 STI.
HKS Oil Coolers use a very high-performance cooling core; HKS Recognizes that on a street-driven vehicle, this can lead to overcooling. As a result, a thermostat is integrated into this kit to prevent such issues from occurring. This thermostat has a high response and is able to react quickly to changes in oil temperature. Once the oil temperature reaches the set level, the oil will flow through the cooler core but bypasses when temperatures drop lower. This allows engine oil to be maintained at the ideal temperature while ensuring the vehicle can heat up in a timely fashion and maintain the perfect operating temp under abuse.
The thermostat relief feature allows for safe operation in times of emergency. In cases where the core or lines become blocked and the oil pressure rises, the thermostat will bypass the core to maintain the correct oil pressure and prevent damage to the oil lines and fittings.
Stainless braided hoses are chosen for increasing durability. Hose lengths and fitting types are tailored to each vehicle application to ensure easy and tidy fitting while preventing connection errors.
