Description
The Mishimoto MMOC-34SL is a 34-row stacked-plate oil cooler finished in Sleek Silver, engineered by Mishimoto to pull excess heat out of your engine oil before it can compromise lubrication. Built with a bar-and-plate performance core and -10AN male AN Flare inlet and outlet fittings, this cooler is designed to bolt onto a wide range of builds using its eight universal mounting holes. A subtle Mishimoto logo appears on one side of the silver finish, distinguishing it from the logo-free Stealth Black option.
Engine oil is formulated to work within a specific temperature and pressure window, and that window is easy to exceed once a vehicle is heavily modified or driven hard. This Mishimoto oil cooler addresses that problem directly: the 34-row stacked-plate core provides substantial surface area for heat transfer, helping bring oil temperatures back into their effective range so lubrication and reduced wear are maintained. As a Mishimoto Cooling product, it’s built to work with Mishimoto -10AN braided hoses and -10AN aluminum fittings for a complete, leak-resistant oil cooler installation, and every unit is backed by the Mishimoto Lifetime Warranty.
Vehicle Applications
This 34-row oil cooler is a universal-fit component rather than a cooler engineered for one specific chassis or engine. Mishimoto equips the core with eight universal mounting holes, giving installers the flexibility to mount it in the location that best suits their particular engine bay and airflow needs. Because application data wasn’t tied to a specific make, model, or year for this listing, it’s suited to owners who need a universal oil cooler solution for vehicles that have been extensively modified or that see high-stress driving conditions where extra oil cooling capacity is beneficial.
