Part No.: 27002-AN005 | Available at Just Bolt-On Performance Parts

Upgrade the cooling efficiency and longevity of your 2017–2024 Nissan R35 GT-R’s GR6 dual-clutch transmission with the HKS DCT Fluid Oil Cooler Kit. Designed to enhance transmission stability under high-performance driving conditions, this kit is engineered for track and street use, ensuring optimal cooling, reduced heat soak, and improved clutch and transmission protection.

Track-Tested Cooling Performance for the GR6 Dual-Clutch Transmission

The HKS DCT Fluid Oil Cooler Kit is built to combat high transmission fluid temperatures that can lead to performance loss and premature wear under aggressive driving conditions.

✔ Optimized cooling to maintain transmission performance on track and street
✔ Protects the GR6 dual-clutch transmission and clutch system from overheating
✔ Designed specifically for the 2017+ R35 GT-R with enhanced cooling capabilities

With HKS’ extensive testing, this kit provides a consistent and stable transmission feel, allowing you to push your GT-R harder without overheating concerns.

Dry Carbon Fiber Oil Cooler Duct for Maximum Airflow

HKS developed a lightweight yet highly durable dry carbon fiber oil cooler duct, specifically designed to fit the 2017+ R35 GT-R front bumper.

✔ Constructed from premium dry carbon fiber for weight savings and durability
✔ Designed for maximum airflow to direct cool air over the entire cooler core
✔ Specialized dry carbon partition ensures uniform air distribution, improving cooling efficiency

By integrating this advanced cooling duct, the system ensures even heat dissipation across the cooler core, further stabilizing transmission fluid temperatures under heavy load.

High-Performance 15-Row Oil Cooler Core

At the heart of this system is a high-efficiency, 15-layer oil cooler core, placed inside the left fender to maximize cooling potential.

✔ Core Size: 200mm x 220mm x 48.5mm
✔ 15-layer design for optimal heat dissipation
✔ Ensures transmission fluid remains at ideal operating temperatures

By keeping the DCT fluid within optimal temperature ranges, this kit prevents power loss, clutch degradation, and excessive wear on transmission components.

Specially Designed Washer Tank for Proper Fitment

Since the oil cooler system requires relocating the stock washer tank, HKS includes a specially designed replacement washer tank in the kit.

✔ Custom-fit washer tank integrates seamlessly with the GT-R’s engine bay
✔ Allows proper clearance for the new oil cooler setup
✔ Note: The stock washer fluid level sensor cannot be attached to the new tank

This bolt-on solution ensures that all necessary components fit without compromising function or reliability.

Direct Fitment with Minimal Modifications

While designed for a direct fit on the 2017+ R35 GT-R, minor bumper modifications are required for proper installation.

✔ Designed specifically for the 2017+ R35 GT-R models
✔ Fits inside the left front fender for an OEM-like fitment
✔ Bumper modification required for proper duct placement
✔ Not confirmed for GT-R NISMO models

This HKS cooling solution ensures your transmission operates at peak efficiency, whether you’re pushing your GT-R to its limits on track days or spirited street drives.
