The Mishimoto Oil Cooler Kit, specifically designed for the 2016-2018 Mazda MX-5 Miata, aims to significantly improve cooling efficiency for track-day enthusiasts. Recognizing that the stock 2016 Miata lacks a factory oil cooler, this kit provides a crucial upgrade to maintain optimal oil temperatures during demanding driving conditions. At the heart of the kit is a 19-row stacked-plate oil cooler, engineered to be mounted directly in front of the radiator using application-specific aluminum brackets for maximum airflow. This setup has been shown to decrease oil temperatures by up to 57°F (29.5°C). The system also features pre-made stainless steel braided oil lines equipped with durable -10AN fittings, facilitating a straightforward installation. Furthermore, the kit contributes to an increased oil capacity of 0.75 quarts. Buyers have a choice between a billet aluminum thermostatic or non-thermostatic oil sandwich plate, allowing for customization based on specific needs and preferences. The oil cooler itself is available in either a Sleek Silver or Stealth Black powdercoat finish. All Mishimoto Miata parts, including this oil cooler kit, are backed by the Mishimoto Lifetime Warranty, ensuring long-term performance and reliability.
