Description
The Mishimoto 2019+ Mazda Miata ND2 Oil Cooler Kit (MMOC-MIA-19T) is a direct-fit Cooling upgrade engineered specifically for the ND2 chassis, replacing the factory liquid-to-liquid oil cooler/warmer with a purpose-built 19-row stacked-plate oil cooler. Mishimoto engineers recorded consistent oil temperature decreases of up to 57°F (29.5°C) when testing the kit with the non-thermostatic sandwich plate, giving track-driven Miatas the cooling margin the factory setup can’t sustain under sustained load.
As a dedicated Mishimoto oil cooler kit, this system pairs a 19-row stacked-plate core with application-specific aluminum mounting brackets that position the cooler directly in front of the radiator for maximum airflow. -10AN braided stainless-steel lines route oil from a direct-fit billet-aluminum sandwich plate and stainless-steel adapter to the cooler, and the kit increases oil capacity by 0.75 qt for added cooling capacity. Buyers choose between a thermostatic sandwich plate, recommended for daily-driven Miatas, or a non-thermostatic plate suited to hot climates and dedicated race builds, along with a Sleek Silver or Stealth Black powder-coated finish. Every Mishimoto cooler in this kit ships with the Mishimoto Lifetime Warranty.
