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

Upgrade your 1999-2005 Mazda Miata NB with the Mishimoto thermostatic oil cooler kit designed to combat high oil temperatures during track days or spirited drives. This direct-fit kit replaces the stock liquid-to-liquid cooler and reduces oil temps by 10°F (5.6°C) on 65 mph highway cruises keeping engine components protected. Ideal for stock boosted or naturally aspirated Miatas it mounts cleanly with room for intercoolers and turbos.

Key Features

  • Thermostatic Sandwich Plate: Billet aluminum plate opens at 180°F (82°C) to regulate flow preventing overcooling in cold climates while ensuring optimal oil temperature
  • Oil Temperature Reduction: Proven 10°F drop during testing on highway cruises protects pistons rings and vital engine parts from heat damage on track
  • Air-Ducting Mounting Bracket: Channels cool air directly to the cooler and positions it behind the bumper for intercooler and forced induction clearance
  • Pre-Made Stainless Steel Lines: Durable braided -10AN lines with high-quality fittings for leak-free installation and long-term reliability
  • 20-Row Aluminum Core: 8.7 x 5.9 x 1.6 inch core (221 x 150 x 40 mm) with 11.4 x 8.3 x 2 inch overall size (290 x 210 x 50 mm) for maximum cooling efficiency

Product Notes

  • Essential for turbocharged Miatas or track use where oil heat from turbos or hard laps accelerates wear
  • Maintain oil quality by avoiding both overheating and overcooling for consistent performance
  • Kit arrives fully assembled ready for bolt-on installation

Installation Notes

  • Professional installation recommended.
  • Direct bolt-on design uses existing factory mounts no cutting or drilling required
  • Includes all necessary hardware sandwich plate lines and brackets for 99-05 Miata
