An often over looked area in performance upgrading is one of the most important - the engines lubrication and cooling system. If you drastically increase the power output of your engine or operate it under extreme conditions, it is highly recommended to improve or add to the cooling system.

One of the easiest ways is to use a premium synthetic oil. Our GR Oil is comprised of highest automotive grade synthetics and is enhanced even further with specially engineered additive packages, to optimize performance in a tuned engine, enhance viscosity under high heat and resist oil break down.

Upgrading the engine cooling system will also aid in reducing overall engine temperatures. The key point is the radiator and coolant accessories. Using similar inner-fin technology learned from our intercooler, our two row full aluminum GReddy Radiators maintain constant water temperatures even in extreme conditions.

Especially important in turbocharged applications, the addition of a GREX Oil Cooler Kit will increase oil capacity, decrease oil temperatures and keep oil pressure up, thereby extending the life of your turbo & engine componets. Essential in protecting both engine and oil life under high strain environments.

Additional Oil and Cooling accessories we offer are : high performance Oil Filters, Oil Filter Relocation Kits, Oil Block Adapters, Hi-pressure Radiator Caps, Radiator Breather Tanks, and Air Diversion Panels.
