Product Description

The HKS 15004-AT014 S-Type Oil Cooler Kit is a vehicle-specific engine oil thermal management solution engineered for the Toyota GR86 (ZN8) and Subaru BRZ (ZD8) equipped with the FA24 2.4 L engine. Under high-load conditions such as spirited street driving or track use, the factory engine oil can exceed safe temperature limits, leading to reduced lubrication efficiency and potential long-term wear. This kit addresses that by adding a dedicated high-capacity 12-row oil cooler core alongside a thermostat-equipped sandwich adapter that prevents oil from overcooling during regular driving and ensures optimal lubrication temperatures when needed.

Designed for seamless integration into the GR86/BRZ cooling architecture, the S-Type Oil Cooler places the core inside the left front fender area with adjustable ducting that can accommodate different bumper designs or performance front-end packages. The included aluminum washer tank relocates out of the way to make space for the plumbing, and mesh-style hoses with premium fittings improve durability over extended use. Press-formed louvers help vent hot air from the wheel well while protecting the core from debris. This kit is ideal for enthusiasts who push their FA24 engines hard - whether naturally aspirated or with forced induction - and want to maintain consistent oil temperatures for performance and engine longevity.
