HKS Water Cooled Oil Cooler Kit Honda S660

With their Water Cooled Oil Cooler Kit Honda S660, HKS has made it possible to maintain stable oil temperature regardless of the engine layout. By replacing the muffler, tuning the ECU with Flash Editor, and even installing a turbo kit, the S660 can be turned into an engine that runs smoothly up to high rpms. Higher output inevitably leads to higher oil temperatures, but the mid-engine layout makes it impossible to achieve an efficient layout with a conventional air-cooled oil cooler.
