Upgrade your cooling system with the Mishimoto MMRAD MIA 90 performance aluminum radiator compatible with Mazda MX 5 Miata 1990 97 models. This direct fit unit drops right in without cutting or modifications. Designed for automotive enthusiasts, it delivers up to date cooling capability in a classic chassis.

Massive 3-Row Cooling Core

One of the biggest upgrades is the:

• Thick 3-row brazed aluminum core

This dramatically improves:

• Heat dissipation
• Coolant stability
• Thermal efficiency
• Sustained cooling performance

Especially beneficial during:

• Spirited driving
• Track sessions
• Turbocharged operation
• Summer traffic
• High-RPM pulls

Where stock Miata cooling systems occasionally begin emotionally overheating.

Featuring a three row brazed aluminum core, this radiator offers exceptional heat dissipation to lower engine temps under hard driving or in hot climates. As cooling trends continue to favor higher efficiency upgrades in both track and day by day drivers, this unit helps to keep your vehicle running cooler and more reliably.

Full Aluminum Construction

Unlike factory radiators that commonly use:

• Plastic end tanks
• Aging OEM materials
• Crimped seams

The Mishimoto radiator features:

• TIG-welded aluminum end tanks
• Fully aluminum construction
• Reinforced cooling structure

Helping improve:

• Durability
• Pressure resistance
• Cooling consistency
• Long-term reliability

Because 30-year-old cooling systems plus enthusiastic driving eventually becomes a mechanical science experiment.

Built for durability, TIG welded end tanks make stronger structural strength even as resisting thermal stress. A magnetic drain plug helps catch metal particles, protecting engine internals over the years. Noticeably cooler running and easy installation are key benefits.

Magnetic Drain Plug Protection

One major advantage is the included:

• Magnetic drain plug

This helps:

• Capture metal particles
• Improve cooling system cleanliness
• Reduce contamination risk
• Enhance long-term reliability

Especially useful for:

• High-mileage Miatas
• Track cars
• Turbocharged builds

Because old engines occasionally create mystery glitter internally.

Additional enhancements include a high pressure radiator cap that raises coolant boiling point for more robust cooling performance, and an authentic serial number plate that reinforces product legitimacy and brand accountability.

Perfect for Turbo & Track Builds

This radiator is especially valuable for:

• Turbocharged BP builds
• Supercharged Miatas
• Drift cars
• Time attack setups
• Aggressive street builds

Improved cooling helps reduce:

• Heat soak
• Coolant spikes
• Thermal fatigue
• Power loss during extended driving

Especially because turbo Miatas generate heat levels hilariously disproportionate to their adorable size.

Mishimoto has been engineering performance cooling solutions since 2005 and continues to stand firmly in the back of each product. You get premium materials, thoughtful engineering, and full reinforce you’ll rely on each mile.

Better Reliability for Spirited Driving

Aggressive driving creates:

• Sustained high RPM operation
• Elevated coolant temperatures
• Continuous thermal load
• Increased engine bay heat

A larger 3-row radiator helps maintain:

• Stable temperatures
• Better cooling consistency
• Improved reliability
• Reduced overheating risk

Especially important because overheating ruins otherwise perfect top-down canyon drives immediately.

Compatibility: Direct fit design compatible with Mazda Miata 1990 97 manual transmission models ensuring OEM style installation
Optimized Performance: 3 row brazed aluminum core dissipates heat quickly to reduce engine temps under load and spirited driving
Durable Construction: TIG welded end tanks and magnetic drain plug combine strength with corrosion resistance and metal particle protection
Enhanced Cooling Efficiency: Includes a high pressure cap to raise coolant boiling point for more robust cooling performance
Peace of Mind: Constructed with high-performance materials and backed by Mishimoto’s high standards for durability and quality

OEM-Style Direct Fit Installation

The radiator is engineered for:

• Direct-fit installation
• OEM hose compatibility
• Factory mounting integration

Typical installation requires:

• Coolant drain
• Socket set
• Hose clamp pliers
• Approximately 1-3 hours

No major:

• Fabrication
• Cutting
• Custom mounting required

Which is fortunate, because Miata projects already spiral into suspension and wheel upgrades fast enough naturally.

Why Upgrade the NA Miata Radiator?

Common reasons Miata owners upgrade radiators include:

• Aging OEM radiator failure
• Turbocharging
• Track overheating concerns
• Preventative maintenance
• Cooling reliability improvements
• Spirited driving thermal management

A performance radiator remains one of the smartest upgrades for NA Miatas because:

• Heat kills consistency quickly
• Track driving exposes cooling limitations fast
• Turbo builds create significant thermal load

Especially once boost pressure arrives.

Final Verdict

For 1990-1997 Mazda MX-5 Miata owners wanting improved cooling performance and long-term reliability, the Mishimoto Performance Aluminum Radiator delivers serious thermal management upgrades with rugged aluminum construction.

Key benefits include:

• Thick 3-row aluminum core
• TIG-welded end tanks
• Magnetic drain plug
• Improved heat dissipation
• Ideal for turbo and track builds
• Direct-fit installation

Most importantly, your Miata finally stops treating every spirited drive like a coolant temperature emergency.
