This HKS DCT Cooler Kit is exclusively engineered for the 2007-2010 R35 models, featuring an advanced oil cooling system for the GR6 dual-clutch transmission. Designed to maintain a stable shifting experience from intense circuit sessions to everyday city driving, it offers reliable protection for both the clutch and transmission. This cooler kit not only enhances cooling efficiency but also ensures consistent oil temperature, promoting smooth shifting across different driving conditions. By managing peak oil temperatures, it extends the oil life cycle and further reduces maximum water temperatures, contributing to overall engine and transmission longevity.

Remark

・MT oil is required separately. (Approx. 2L additional) ・Front bumper will be modified (duct section) ・Washer pump harness must be extended. (0.5SQ 250mm x 2 required separately) ・Washer fluid volume will be 1L compared to the OEM 1.5L. ・Washer fluid volume sensor cannot be installed. (No warning displayed) ・The operating sound of the MT oil pump (OEM) will be easier to hear.

Application

• GT-R R35 (2007, 2008, 2009, 2010)

Features

• The oil cooler core is located on the front left fender to ensure maximum cooling performance .
• The core is equipped with a dedicated air duct (made of FRP) for efficient cooling.
• #10 size piping is used to minimize changes in pipeline resistance and ensure sufficient oil flow to the core.
• A new oil extraction attachment has been designed specifically for the GR6 . The genuine heat exchanger and HKS thermostat are incorporated into the system, stabilizing the oil temperature in a short time even during cold starts. The poor shift feeling at low temperatures is kept to a minimum (same as genuine).
• In tests conducted by professional drivers on the Fuji Speedway course, it was confirmed that continuous laps were possible with a maximum oil temperature of 127°C . At the same time, it was confirmed that the water temperature dropped by up to 5°C . (In the normal version, the temperature reached 135°C after 5 laps, and the test was stopped.)
