✅ Vehicle Fitment
Designed for:
-
Mazda MX-5 Miata
-
Compatible with Manual & Automatic Transmission models
Direct bolt-on design for NC chassis applications.
Cooling is absolutely crucial during high performance driving. Maintained high load, high RPM instances dramatically increases heat produced by the engine requiring a lot more from the vehicle’s cooling system.
Megan Radiators are comprised completely of aluminum. From the tanks to the primary core. Aluminum tanks are a great upgrade over the plastic usually found on factory radiators which are known to crack and leak especially as they age. The larger heat exchanging core is not only more efficient at transferring heat from the coolant, but also increases total coolant carrying capacity.
Why Upgrade the Megan MR-RT-MMX506 MX-5 NC Radiator?
Factory radiators can:
-
Struggle under sustained high RPM
-
Lose efficiency over time
-
Develop plastic tank fatigue
An all-aluminum design eliminates plastic end tanks and improves thermal transfer.
Designed to as a complete bolt-on application, Our radiators are designed to comply with factory components such as fans and A/C condensers however due to the slight increase in overall size. Upgrading to high capacity, slim radiator fans is suggested.

Construction Design: 40mm Heat Exchanger Thickness
Improves cooling efficiency by 35 – 45% temp, Compatible / Replacement For 2006-2015 MX-5 Miata Automatic/Manual Transmission (NC 3rd Gen)
Aluminum radiators mark a modern advancement in cooling. Not only does the material dissipate heat at close to double the rate compared to brass, but also reduced the overall weight of the vehicle and provides a stronger and more durable core and tube design
Megan MR-RT-MMX506 MX-5 NC Radiator Performance Benefits
-
Lower coolant temperatures
-
Improved consistency during track sessions
-
Better heat management for tuned or boosted builds
-
Increased reliability in hot climates
If you’re pushing your NC hard, cooling upgrades are cheap insurance.
Installation Notes
-
Compatible with MT and AT, but confirm transmission cooler configuration for AT models.
-
Inspect hoses and thermostat during install.
-
Properly bleed cooling system (Miatas are sensitive to trapped air).
-
Use recommended coolant mix.
Cooling system maintenance on an NC is not optional if you track the car.
