HKS S-Type Oil Cooler Kit Subaru BRZ (–2016 FA20)

The HKS Oil Cooler Kit for the Toyota 86 ZN6 and Subaru BRZ ZC6 is designed for vehicles requiring stable oil temperatures under high load. The core mounts inside the fender, allowing installations that would normally conflict with front-mounted intercoolers or GT Supercharger setups. This makes the kit ideal for forced-induction builds, upgraded turbo vehicles, and NA cars used for track driving.

Product Overview

The inner-fender mounting position keeps the front of the car free for intercoolers and improves packaging for high-performance setups. A dedicated air guide directs airflow into the cooler for higher efficiency. A special spacer and centre bolt are included to prevent interference near the oil filter mounting surface, ensuring proper fitment.
