HKS DCT Cooler Kit for CBA-R35 Nissan GT-R

The HKS DCT Cooler Kit for the GT-R was designed to enhance shift engagement and prevent overheating of the clutch and transmission in both street and racing conditions. It helps to maintain lower oil temperatures in the transmission, which extends the life of the oil. The kit integrates with the factory water-cooled transmission cooler, contributing to the reduction of the GT-R’s overall water temperature.


  • For optimal cooling performance, the DCT cooler core is positioned at the front left fender.
  • An air duct made of Fiber Reinforced Polymer (FRP) specifically created for the R35 GT-R is included in the kit to improve air flow to the core.
  • The installation of a larger -10 size oil line reduces resistance within pipes and improves flow, ensuring a proper supply of oil.
  • The DCT Cooler integrates the stock heat exchanger and HKS thermostat of the transmission. With a specially designed oil outlet attachment, it stabilizes the oil temperature in a quicker time frame, leading to noticeable improvement in shifts even after a cold start.
  • During trials at Fuji Speedway, the average reduction in water temperature was 5°C (9°F), allowing for consistent laps to be completed with a constant oil temperature of 127°C (260°F).
  • The original transmission cooling system from the factory is a water-cooled transmission cooler.
  • The fuel safe mechanism is triggered when the oil temperature reaches 140℃ to 145℃.
  • It is recommended by Nissan to replace engine oil when the oil temperature exceeds 140℃.
  • If the temperature of the 4WD clutch rises, even if the transmission oil temperature is below 140℃, the drive mode will switch to 2WD. A warning message will appear if there is an abnormal increase in oil temperature of the drive-train components and a persistent improper revolution difference between the front and rear wheels.
  • The kit includes a newly designed aluminum washer tank specifically for the R35, with a stock feed-water inlet for ease of maintenance.
  • The R35 GT-R is equipped with aluminum pipes designed specifically for the engine and its lower area. These pipes reduce weight and enhance the appearance of the engine compartment.

About HKS

In 1973, two experienced engineers, Hiroyuki Hasegawa and Mr. Kitagawa, had a vision to create high-performance engines and parts that were not being produced by major original equipment manufacturers. With funding from Sigma Automotive Co., Ltd, the duo started their journey in a barn near Mount Fuji, Japan, modifying gasoline engines. The following year, Hasegawa designed the first aftermarket turbocharger for passenger vehicles, setting a new standard in the aftermarket performance sector. HKS continued to innovate, introducing the first electronic turbo timer and boost controller, along with piggy-back fuel computers and advanced fuel management devices, becoming a leader in the Japanese aftermarket performance scene.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions.
