The HKS S-Type Oil Cooler Kit is engineered to maintain stable oil temperatures in the Nissan Skyline R32 GT-R equipped with the RB26DETT engine. Under aggressive driving or track conditions, excessive oil temperatures can reduce lubrication efficiency and accelerate engine wear. This complete oil cooler system is designed to prevent oil breakdown while supporting consistent engine performance and long-term reliability.
At the core of the system is a high-efficiency 15-row oil cooler designed to deliver excellent heat dissipation without excessive pressure loss. An integrated thermostat actively manages oil flow, routing oil through the cooler only when temperatures exceed the optimal range. This ensures faster warm-up during cold operation while maintaining ideal oil temperatures during high-load driving.
The thermostat also incorporates a safety bypass function that maintains oil pressure in the event of line or core blockage, protecting the engine and oiling system components. Built from high-quality materials and engineered to meet strict durability standards, the HKS S-Type Oil Cooler Kit is well-suited for spirited street driving, circuit use, and performance-focused builds.
