What is the primary benefit of installing this oil cooler kit?

This kit is designed to lower and stabilize engine oil temperatures, especially under high load conditions like track driving or spirited spirited driving. Maintaining optimal oil temperatures helps protect the engine from wear and ensures consistent performance.

Does the kit include everything needed for installation?

The kit includes the oil cooler, oil block adapter with thermostat, and the necessary hoses. You will need to ensure proper mounting hardware for the cooler core and potentially some basic tools for installation, as per standard automotive procedures.

How does the thermostat in the oil block adapter work?

The thermostat is designed to regulate oil flow to the cooler. It remains closed when the engine oil is cold, allowing it to reach operating temperature more quickly. Once the oil reaches a specific temperature, the thermostat opens, directing oil to the cooler for heat exchange.

Product Details

The HKS oil cooler kit for the JW5 S660 features a 12-row core, a common size that offers a good balance between cooling capacity and airflow for the engine bay. This kit is designed to help manage oil temperatures, especially during demanding driving conditions like track use or spirited canyon runs. Keeping your oil within its optimal temperature range is crucial for engine longevity and consistent performance.

This kit includes a dedicated oil block adapter that integrates seamlessly with the S660's engine. The adapter incorporates a thermostat that controls oil flow to the cooler, ensuring the engine warms up efficiently and then directs oil to the cooler only when necessary. The cooler itself is constructed with HKS's own internal fin design, aiming to maximize heat dissipation while minimizing pressure drop. The black finish on the cooler and associated lines gives a clean, performance-oriented look under the hood.

Installation involves replacing the stock oil filter housing with the included HKS oil block adapter and routing the high-pressure, heat-resistant hoses to the cooler core, which is typically mounted in the front of the vehicle where it can receive ample airflow. While this is a bolt-on kit, careful routing of the lines and secure mounting of the cooler are important for reliability. This kit is a solid choice for S660 owners looking to enhance their engine's cooling system for more aggressive driving.
