HKS Engineering Excellence
This isn’t just a rebranded universal kit. HKS’s S-Type layout uses a front-mounted 15-row core for maximum airflow and efficiency without blocking the radiator. Precision-machined fittings, reinforced stainless hoses, and perfect OEM-style fitment mean this kit bolts on cleanly — no janky “racecar” hacks required.
The included thermostatic sandwich adapter ensures your oil warms up properly before cooling kicks in, making it street-friendly and track-ready. The result? Consistent oil temps, reduced risk of heat soak, and increased reliability during spirited driving or track sessions.
By attaching to GR86/BRZ with oil temperature exceeding 130 degrees Celsius when cycling around the circuit, the oil temperature is suppressed and can be continuously rotated (during FSW short course).
12 rows of oil cooler core mounted in front of the left fender in the bumper while still maintaining the performance of the factory front bumper duct fin.
NA vehicles cool engine oil without affecting the radiator Can be used with GT2 supercharger and pre-installed intercoolers with bolt-on turbo kit (under development). Replace the original washer tank with the washer tank in the kit.
Performance Meets Reliability
With oil temps under control, your GR86 or BRZ can sustain higher loads, longer. That means more consistent lap times, smoother throttle response, and a longer-lasting engine. Combine it with an HKS intake or exhaust, and you’ve got a perfectly balanced setup that’s ready for serious fun.

Flap function at the end of the duct Adjustable oil cooler duct opening to any width for GR86/BRZ bumper opening It can also be used when the supercharger kit is installed.
The inner fender is fitted with press molded louvers. After the core passes through the core is not interrupted by the turbulence inside the tire house and efficiently dissipates hot air while preventing core damage caused by rocks.
A newly developed “Aluminum Extraction Oil Attachment” for GR86/BRZ. Since it is a genuine water-cooled oil cooler, the oil filter is the highest position in the engine room when you install the conventional attachment, but the height of the filter is reduced by 0.9 inches (22 mm) and the height of the filter is lower than the air compap. Prevents oil filter from protruding into engine compartment.
The “Aluminum Extractor Oil Extraction Attachment” has a thermostat to control oil temperature. Avoid overcooling and increase the viscosity resistance of engine oil.
