Mishimoto Black Thermostatic Oil Cooler Kit for 1999-2005 Mazda Miata – Essential Performance Upgrade for Track and Street

Get ready to dominate your track days with the Mishimoto Black Thermostatic Oil Cooler Kit for the 1999-2005 Mazda Miata. If you push your Miata to the limits, you know that high oil temperatures can quickly lead to engine failure. Don’t risk ruining your fun or breaking the bank on costly repairs—equip your Miata with the Mishimoto Oil Cooler Kit to keep your engine running cool, even under extreme conditions.

This high-performance oil cooler is designed for the spirited driver. Unlike the stock liquid-to-liquid oil cooler, which is fine for daily driving, the Mishimoto Oil Cooler is made for aggressive driving and track sessions. Tested to reduce oil temperatures by up to 10°F (5.6°C) during highway cruises at 65 mph, this oil cooler setup can handle the heat, giving you peace of mind during high-intensity driving.

The Mishimoto Thermostatic Oil Cooler Kit features a billet aluminum thermostatic sandwich plate, ensuring your oil reaches the optimal temperature before it flows to the cooler. This prevents overcooling in colder conditions, which can be just as harmful to your engine as overheating.

Perfect for turbocharged or naturally aspirated Miatas, this oil cooler kit also has a unique mounting bracket design that channels air directly to the cooler while leaving room for other upgrades like an intercooler. If you're running forced induction, this cooler becomes essential to keep your oil in check and your performance top-notch.

Key Features & Benefits:

  • Reduces oil temperatures by up to 10°F (5.6°C) to prevent overheating and preserve engine health.
  • Billet aluminum thermostatic sandwich plate for precise oil temperature regulation.
  • Pre-made stainless steel braided lines with durable -10AN fittings for easy installation and maximum durability.
  • Mounting bracket doubles as air ducting, channeling more airflow to the cooler while saving space for intercoolers and other upgrades.
  • Designed for forced induction setups (perfect for turbo or supercharged Miatas).
  • Mishimoto Lifetime Warranty, ensuring quality and dependability for your Miata.

Don’t wait for engine failure to remind you of the importance of oil cooling. Upgrade your Miata with the Mishimoto Thermostatic Oil Cooler Kit and stay ahead of the competition. Buy now and give your Miata the cooling power it deserves—whether on the track or on the streets.
