Mishimoto Silver Thermostatic Oil Cooler Kit for 1999-2005 Mazda Miata
Maximize performance and protect your engine with the Mishimoto Silver Thermostatic Oil Cooler Kit, designed for the 1999-2005 Mazda Miata. Whether you're taking your Miata to the track or pushing the limits on spirited drives, this oil cooler is an essential upgrade for maintaining optimal oil temperatures and ensuring your engine stays cool under pressure.

High oil temperatures can be detrimental to engine components, causing costly repairs and reducing performance. Miatas come equipped with a stock liquid-to-liquid oil cooler, which is adequate for daily driving but falls short during intense track sessions. Mishimoto's thermostatic oil cooler kit is engineered to drop oil temperatures by up to 10°F (5.6°C) during high-speed cruising, keeping your engine running at peak performance and preventing heat damage when you're pushing your Miata to the limit.

Key Features & Benefits:

  • Optimal Oil Cooling: The oil cooler effectively reduces oil temperatures, ensuring maximum engine protection during track days and aggressive driving.
  • Billet Aluminum Thermostatic Oil Sandwich Plate: Regulates oil temperature, preventing overcooling in colder climates and ensuring the oil is at the right temperature before circulating to the cooler.
  • Efficient Airflow Design: The mounting bracket channels airflow directly to the cooler, optimizing cooling performance and making room for other performance upgrades like intercoolers and turbo systems.
  • Perfect for Boosted Miatas: If you’ve got forced induction, this oil cooler kit is a must-have, helping to control the heat generated by your turbo setup and keep oil temperatures in check.
  • Pre-made Stainless Steel Braided Lines: Durable -10AN fittings and pre-assembled lines for easy installation and a secure connection.
  • Lifetime Warranty: Like all Mishimoto products, this oil cooler kit comes with a lifetime warranty, so you can trust it to perform race after race.

Don’t let high oil temperatures slow you down—keep your Miata running cool and performing at its best with the Mishimoto Silver Thermostatic Oil Cooler Kit. Upgrade now for the cooling power your engine demands! Order today and take control of your engine's future!
