HKS 2011-2016 Nissan R34 GT-R DCT Fluid Oil Cooler - 27002-AN004

Part No.: 27002-AN004 | Available at Just Bolt-On Performance Parts

Maximize the performance and longevity of your 2011–2016 Nissan R35 GT-R’s GR6 dual-clutch transmission with the HKS DCT Fluid Oil Cooler Kit. Engineered to enhance cooling efficiency, improve shift engagement, and prevent transmission overheating, this kit ensures consistent performance on both the street and track. With integrated water and oil cooling solutions, this system provides superior temperature regulation, extended transmission oil life, and enhanced drivetrain durability.


Track-Tested Cooling Efficiency for the GR6 Transmission

The HKS DCT Fluid Oil Cooler Kit has been developed through extensive track testing, delivering significant temperature stabilization benefits:

Prevents overheating of the transmission and clutch system
Reduces overall GT-R water temperatures by working alongside the factory cooling system
Enhances transmission oil longevity and improves cold start shift response

Testing at Fuji Speedway demonstrated that water temperatures were reduced by an average of 5°C (9°F), while transmission oil temperatures remained stable at 127°C (260°F) under heavy load—ensuring the GR6 transmission maintains peak performance for extended sessions.


Optimized Cooling System for Maximum Performance

The HKS DCT Fluid Oil Cooler Kit features a strategically placed core and high-flow oil lines to optimize heat dissipation.

Front left fender-mounted core placement ensures maximum cooling efficiency
15-layer, high-performance oil cooler core provides superior heat dissipation
-10AN oil lines increase flow capacity, reducing resistance and improving cooling
HKS thermostat-integrated heat exchanger stabilizes oil temperatures faster

These enhancements ensure that your GT-R’s dual-clutch transmission remains cool and consistent, even during high-performance driving and extended track sessions.


Fiber Reinforced Polymer (FRP) Air Duct for Superior Airflow

To further enhance cooling efficiency, HKS includes a specially designed FRP air duct, which:

Directs fresh air toward the cooler core for optimized heat dissipation
Ensures even airflow across the core, improving temperature regulation
Lightweight and durable construction integrates seamlessly with the GT-R’s bodywork

This precision-engineered air duct works in tandem with the DCT oil cooler core to minimize temperature fluctuations and extend drivetrain reliability.


Enhanced Shift Engagement & Faster Temperature Stabilization

The HKS DCT Cooler Kit works in conjunction with the factory transmission heat exchanger, featuring:

A custom-designed oil outlet attachment for faster oil temperature stabilization
Smoother, more responsive shifts—even in cold start conditions
Optimized cooling characteristics to prevent overheating during extended use

By stabilizing oil temperatures quicker, this system improves shift consistency, protects internal transmission components, and reduces the likelihood of drivetrain overheating warnings.


Aluminum Washer Tank & Engine Bay Enhancements

To accommodate the new cooling system, HKS includes a redesigned aluminum washer tank, which:

Uses a stock feed-water inlet for easy maintenance
Offers a lightweight, durable solution that integrates seamlessly into the engine bay

Additionally, HKS-designed aluminum piping enhances airflow efficiency while reducing weight, providing:

Improved engine bay aesthetics with a clean, high-performance look
Increased durability and weight savings compared to stock components


Direct Fitment with Minimal Modifications

While this DCT cooler kit is designed for bolt-on installation, minor bumper modifications are required for proper placement.

Custom fit for 2011–2016 Nissan R35 GT-R models
Mounts inside the left fender for OEM-like fitment
Bumper modifications required for proper air duct placement
Direct integration with the factory transmission heat exchanger

This race-proven cooling solution ensures your transmission remains protected under high-performance driving conditions.
