Description
The Mishimoto 34-Row Stacked-Plate Oil Cooler (MMOC-34GD) is a Gold-finished, bar-and-plate oil cooler engineered to pull heat out of engine oil before it can compromise lubrication. Built around a 34-row core with dual -10AN male AN Flare fittings, this Mishimoto oil cooler is designed to mount virtually anywhere thanks to its eight universal mounting holes, making it one of the more flexible additions you can make to a vehicle’s cooling system.
Keeping oil temperature in check is one of the simplest ways to extend engine life, especially once a vehicle is modified or driven hard under high-stress conditions. Engine oil is formulated to work within a specific temperature and pressure range, and once that range is exceeded, lubrication suffers and wear accelerates. As a dedicated Mishimoto oil cooler, this 34-row stacked-plate design maximizes surface area for substantial heat transfer while keeping pressure loss to a minimum, helping preserve oil viscosity during aggressive driving. This Mishimoto cooler works as a straightforward oil cooler kit addition — pair it with Mishimoto -10AN braided hoses and -10AN aluminum fittings to complete the installation.
Vehicle Applications
This Mishimoto oil cooler is built as a universal-fit unit rather than a vehicle-specific kit — no dedicated engine codes, chassis codes, or application notes are listed for it. Instead, the eight universal mounting holes give installers the flexibility to fit this 34-row cooler into a wide variety of vehicles and custom cooling setups, making it a practical choice for builds where a fixed-bracket, vehicle-specific cooler isn’t available.
