Improved Cooling Performance

One of the biggest upgrades over the stock radiator is:

• Better heat dissipation
• Improved coolant stability
• Reduced heat soak
• Increased thermal efficiency

Especially beneficial during:

• Drift events
• Track sessions
• Summer driving
• Stop-and-go traffic
• Aggressive canyon runs

Where stock cooling systems occasionally begin emotionally overheating.

Keep your Z at the road and out of the store with the Mishimoto Nissan 350Z Performance Aluminum Radiator! Each and every high-performance vehicle demands a cooling system that may deal with temperatures right through both routine and competitive driving.

Full Aluminum 2-Row Core Design

The Mishimoto radiator features:

• Full aluminum construction
• 2-row cooling core
• Increased thermal surface area

Specifications:

• Overall size: 29.7” x 21”
• Core size: 15.75” x 28.15”
• Core thickness: 1.42”
• Inlet/outlet size: 1.4”
• Tank wall thickness: 0.08”

This improves:

• Heat transfer capability
• Cooling consistency
• Thermal recovery
• Long-term reliability

Especially important because VQ engines generate heat almost as aggressively as they generate memes online.

The Mishimoto 350Z performance radiator features all-aluminum construction and precision robotic TIG-welding for consistency and durability.

Full Aluminum Construction Benefits

Unlike factory radiators that commonly use:

• Plastic end tanks
• Aging crimp seams
• OEM composite materials

The Mishimoto radiator uses:

• Welded aluminum tanks
• Reinforced construction
• Performance-grade materials

Helping improve:

• Durability
• Pressure resistance
• Cooling system longevity
• High-performance survivability

Because aging Nissan radiator plastics plus track abuse eventually becomes a predictable problem.

This radiator includes a thick, 2-row brazed aluminum core in a position to reducing coolant temperatures significantly.

Ideal for Drift & Track Builds

This radiator is especially valuable for:

• Drift cars
• Time attack builds
• Turbocharged VQ setups
• Track-day 350Zs
• Aggressive street builds

Improved cooling helps reduce:

• Heat soak
• Coolant spikes
• Thermal fatigue
• Power loss during long sessions

Especially because drifting somehow converts rear tires directly into engine bay heat.

This radiator also includes a Mishimoto 1. 3 Bar High Pressure Radiator Cap, which effectively raises the boiling point of your coolant to create a safer and more efficient system.

Better Reliability for Daily Drivers

Even naturally aspirated daily-driven Zs benefit from:

• Improved cooling consistency
• Reduced overheating risk
• Better long-term reliability
• Preventative maintenance advantages

Especially important because:

• Most early 350Zs now have high mileage
• Original cooling systems are aging
• VQ engines already run relatively warm from the factory

And spirited driving definitely does not help calm the situation.

The Mishimoto 350Z Performance Aluminum Radiator includes a magnetic oil drain plug with doughty seal and robust threads for durable repeated installation and superior protection against leaks.

OEM-Style Direct Fit Installation

The radiator is engineered for:

• Direct bolt-in installation
• OEM hose compatibility
• Factory mounting integration

Typical installation requires:

• Coolant drain
• Socket set
• Hose clamp pliers
• Approximately 2-4 hours

No major:

• Fabrication
• Cutting
• Custom mounting typically required

Which is fortunate, because Z engine bays already become crowded immediately after modifications begin.

The sturdy aluminum end tanks feature a subtle brushed finish that complements any engine bay perfectly! As with any our products, this radiator includes the Mishimoto , ensuring superior product quality and craftsmanship.

Compatible Nissan 350Z Models

The Mishimoto Performance Aluminum Radiator is compatible with:

• 2003 Nissan 350Z
• 2004 Nissan 350Z
• 2005 Nissan 350Z
• 2006 Nissan 350Z

Perfect for:

• Street-driven Zs
• Drift builds
• Track cars
• Canyon setups
• Turbo VQ projects
• Daily-driven sports cars

Because no 350Z owner leaves the exhaust stock for more than approximately three business days.

Overall Size: 29.7” x 21” x 1.92” / Core Size: 15.75” x 28.15” / Rows: 2
Inlet & Outlet: 1.4” / Core Thickness: 1.42” / Tank Wall Thickness: 0.08”

Why Upgrade the Nissan 350Z Radiator?

Common reasons 350Z owners upgrade radiators include:

• Track overheating concerns
• Drift cooling demands
• Aging OEM radiator failure
• Turbocharging
• Preventative maintenance
• Cooling reliability upgrades

A performance radiator remains one of the smartest upgrades for VQ-powered cars because:

• Heat kills consistency quickly
• Drift and track driving create serious thermal load
• Factory cooling systems struggle under repeated hard driving

Especially once the limiter starts seeing regular use.
