4SRC Nissan GT-R R35 High-Performance CNC Engine Oil Cooler

CNC Machined • OEM Bolt-On • Double Oil Capacity

Upgrade your Nissan GT-R R35’s cooling system with the 4SRC High-Performance CNC Engine Oil Cooler, engineered for enthusiasts who demand maximum cooling efficiency without compromising OEM fitment.
With double the oil capacity of the factory cooler and precision CNC-machined billet aluminum end tanks, this is the ultimate solution for both OEM replacement and performance upgrades.

Why Upgrade Your GT-R’s Oil Cooler

The factory GT-R R35 oil cooler holds only 550cc of oil, which can quickly overheat under spirited driving or track conditions.
Overheated oil leads to reduced viscosity, lower oil pressure, and increased engine wear — especially on tuned or high-power builds.

The 4SRC CNC Engine Oil Cooler increases oil capacity to 1100cc and utilizes a high-capacity multi-fin core to significantly improve thermal management, keeping your VR38 engine protected even in the most demanding environments.

4SRC Advantage

Frequently Asked Questions

Q: Why should I upgrade my GT-R oil cooler?
A: The OEM cooler has limited capacity and struggles under demanding conditions. The 4SRC CNC Oil Cooler doubles oil capacity and enhances heat dissipation, keeping oil temps stable even during aggressive driving or track use.

Q: My GT-R is an older model — is this upgrade relevant for me?
A: Absolutely. On many higher-mileage GT-Rs, especially in regions like the UK and Northern Europe where road salt is used during winter, OEM oil coolers often develop leaks as the cast aluminum end tanks corrode over time.
Replacing the OEM unit can be very expensive.
The 4SRC CNC Engine Oil Cooler provides a cost-effective, high-performance solution with CNC-machined billet end tanks that are far more resistant to corrosion and long-term damage.

Q: Is installation difficult?
A: No. The 4SRC cooler is a direct OEM bolt-on, fully compatible with factory mounting points and airflow ducts — no modifications required.

Q: Will this work with my existing oil lines?
A: Yes. The 4SRC cooler retains the factory oil line geometry and fittings, so installation is straightforward and leak-free.

Q: Is this suitable for track use?
A: Definitely. With double the oil capacity and a high-capacity multi-fin core, the 4SRC CNC cooler is ideal for high-power builds and sustained track conditions.
