A staple for Grassroots, our #1 selling Oil Cooler Kit.

Simple installation is key for this direct-fit oil cooler kit. A vital upgrade to any performance/track builds for added cooling and engine bay space. The oil leaves the block and travels through our length high temperature/high-pressure lines. Grassroots line of performance oil coolers can be used for a variety of oil types, increasing cooling efficiency and oil capacity. Classic design and proven engineering, this 2" thick dual core oil cooler kit allows your oil to maintain peak performance temperature, also aiding the engine cooling system from heat-soaked internals. 


  • Specified line length for a better fit and more ground clearance
  • Upgraded hardware for quicker and easier servicing
  • 90-degree fittings on all line ends for better flow
  • Bracket design upgrade for easier installation


**NOTE Does not fit 2012+ or any AWD models without MINOR modification.   


**Upgrade to thermostatic for optimal street and track use.

**Add a Performance Oil Filter for maximum flow and protection

For Street and Track applications, the thermostatic plate opens at 187.F degrees. This set up allows your vehicle to maintain optimal operating temperatures at all times. If your vehicle is not in constant demand of aided oil cooling, the thermostatic valve will remain shut and your oil system will operate as normal with no interruption. When heavy load and increased temperature occur, the automatic valve will allow the oil to flow through the oil cooler and reduce temperatures to peak performance. Version 3 has two ports for oil feed or oil sensor usage.
