The HKS Water Cooled Intercooler Kit for S660 is well known for its excellent cooling performance, and has been renewed with "lightweight black mesh hose".
Features
- Approximately 20% lighter than stainless steel mesh hose
- Stainless steel mesh hose (HKS product) 310g/m
- Black mesh hose (newly adopted product) 250g/m
- This kit uses a black mesh hose and black and silver fittings.
- The hose and fittings are pre-assembled, just like existing kits.
- The angled fitting has a swivel structure that makes it easy to adjust twisting during installation.
- By installing an HKS water-cooled intercooler, you can achieve stable cooling performance without being affected by the wind while driving.
- By installing a separate radiator for the intercooler, there is no effect on the engine coolant temperature.
- When the HKS water-cooled intercooler is installed, stable cooling performance is ensured, and 20 minutes of continuous full throttle driving is possible without knock retard.
- Compared to the air-cooled type, the core is smaller, and the intake temperature is more stable.
- In the test data below, the I/C outlet temperature for the stock I/C was 92°C about 5 minutes after the start of driving, and the air-cooled prototype I/C was 89°C.
- In contrast, the water-cooled I/C succeeded in stabilizing the temperature at 57°C even after driving for more than 20 minutes.
Notes
- Additional parts required:
- Cooling water volume: Use about 3.5L coolant.
- Relay: Usable power approx. 200W x 1
- Fuse holder: Allowable current approx. 20A x 1
- Connection terminal: Appropriate amount
- Wiring cord: AV2.00sq, Maximum allowable conductor temperature 80℃ or higher, 5m

HKS was founded in October 1973 by Hiroyuki Hasegawa, a former Yamaha engineer, and Goichi Kitagawa, with start-up capital from Sigma Automotive; the name comes from Hasegawa, Kitagawa and Sigma. It began in a small shed at the foot of Mount Fuji, in Fujinomiya, Shizuoka, and is still based there.
In 1974 HKS built one of the first bolt-on turbo kits, for the Nissan L20 engine in the Skyline, raising output from 115 to 160 PS. Turbocharging made its name; today it also makes exhausts, springs, shocks and coilover suspension, and it marked its 50th anniversary in 2023.
