COBB Tuning announces the availability of the Limited Edition Secondary Oil Cooler kit for the Nissan GT-R R35. The COBB Secondary Oil Cooler reduces high engine oil temperatures that occur during extreme driving conditions. This kit utilizes an auxiliary oil cooling core that seamlessly integrates with the OEM oil cooling system, significantly reducing oil temperatures without compromise. Whether pounding around the racetrack or canyon carving during blistering heat, the COBB Secondary Oil Cooler lets your GT-R keep its cool.

Additional horsepower, high ambient temperatures, high altitude and aggressive driving can all contribute to elevated oil temperature. Lower oil temperature ensures better engine protection and longer engine life. Extensive racing and testing data shows that the COBB Secondary Oil Cooler is capable of reducing oil temperatures from extreme peaks of 130C/266F (OEM redline) to acceptable operating temperatures in the 110C/230F range.

This elegantly engineered kit sits opposite the OEM oil cooler in the unused driver side bumper duct. The design is optimized to work with the OEM oil cooler duct, which is included in this kit. Oil flow return from the OEM oil cooler is diverted to the COBB Secondary Oil Cooler for an additional oil cooling stage before being redirected back to the OEM oil return.

Execution of the COBB Secondary Oil Cooler kit leaves nothing to be desired. A Mocal air-to-oil core is used for efficiency and durability. The core is mounted to the chassis using a custom CAD designed aluminum bracket that is designed to work with the included OEM oil cooler duct. The adaptor fittings are custom CAD designed and CNC machined aluminum with black anodizing. All hose ends are high quality aluminum -10 AN fittings with an attractive black and titanium anodized finish. Hoses are preassembled using smooth bore, lightweight synthetic rubber interiors with black nylon overbraid and encased in XRP Fyrefoil 2 radiant heat shielding for additional thermal resistance. The replacement gaskets are Nissan OEM parts.

The Limited Edition COBB Secondary Oil Cooler for the Nissan GT-R R35 is the most comprehensive solution for managing engine oil temperature. Install a COBB Secondary Oil Cooler on your GT-R R35 and drive at the limit without distraction.

Is it not possible to use this radiator for transmission cooling?

Yeah that is what I want, I would rather spend the price of a few track day inspections on a tranny oil cooler that works - unlike the Nissan one that was engineered to over heat, leading to many, many profitable post track day inspections for Nissan.

I agree. Even running Stage 2 Cobb hard on track, I never see my engine oil temps get much above 110c when the trans is over 120.

So I want a decent trans cooler NOW please Ben! :wavey:

Hi Ben,
Any detail on the oil pressure reduction when using this kit in addition to the OEM cooler?

Cheers, Ian
