Mishimoto 99-05 Mazda Miata Thermostatic Oil Cooler Kit - Black

If you're taking your 1999-2005 Mazda Miata out for track days or spirited drives, you know how quickly oil temperatures can climb. High oil temps can seriously damage engine components, turning a fun day into an expensive repair. While the stock liquid-to-liquid cooler is fine for daily driving, it just doesn't keep up when you're pushing the car hard.

This Mishimoto thermostatic oil cooler kit is designed to manage those high temperatures. During testing, it dropped oil temperatures by about 10 degrees Fahrenheit during highway cruising, and it's even more effective on the track. The kit includes a billet aluminum thermostatic sandwich plate, which is important because it ensures your oil reaches its optimal operating temperature before it flows to the cooler. This prevents overcooling, which can be just as bad as overheating, especially in colder climates. The mounting brackets are cleverly designed to act as ducting, channeling air directly to the cooler, and they position the cooler away from the front bumper, leaving room for other upgrades like an intercooler if you're considering forced induction. Turbos also add heat to the oil, making this cooler a vital addition for boosted Miatas.

The kit comes with pre-made stainless steel braided lines with durable -10AN fittings, and it's backed by the Mishimoto Lifetime Warranty. This means you can rely on this oil cooler to keep your engine protected lap after lap.
