hks oil cooler kit mazda rx-7 fd3s 15004-az002

Optimum size of the core and layout design improves cooling performance.

With the use of a new core, both cooling and pressure drop prevention are balanced at a high level. Some vehicle applications contain air guides which maximize the air flow through the oil cooler core during vehicle operation, even in drifting applications where the car may not be facing in the direction it is pointing.
* Some kits are the factory replacement type.
