Improved Cooling Performance

One of the biggest upgrades over the factory radiator is:

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

Especially beneficial during:

• High-RPM driving
• Track sessions
• Turbocharged operation
• Summer traffic
• Aggressive canyon driving

Where stock cooling systems occasionally begin emotionally overheating alongside the driver.

A Mishimoto performance aluminum radiator is the ideal upgrade to the stock Honda Prelude radiator.

Full Aluminum 2-Row Core Design

The Mishimoto radiator features:

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

Specifications:

• Overall size: 27.4” x 17.8” x 2.47”
• Core size: 24.45” x 16.85”
• Core thickness: 1.97”
• Inlet size: 1.25”
• Outlet size: 1.5”
• Tank wall thickness: 0.08”

This improves:

• Heat transfer efficiency
• Coolant stability
• Airflow performance
• Long-term cooling consistency

Especially important because H22 engines love revving almost as much as they love generating heat afterward.

Designed and engineered to maximize cooling efficiency, boost engine functions and most importantly offer protection to your car from overheating.

Full Aluminum Construction Benefits

Unlike factory radiators that commonly use:

• Plastic end tanks
• Aging seals
• Crimped factory seams

The Mishimoto radiator uses:

• Welded aluminum tanks
• Reinforced performance construction
• Durable aluminum materials

Helping improve:

• Durability
• Pressure resistance
• Long-term reliability
• Cooling system longevity

Because 25-year-old plastic radiator tanks and VTEC abuse are not exactly ideal life partners.

Whether you’re a day-to-day driver or you are taking your car to the track, installing an upgraded radiator is very important if you wish to lower your risk of engine failure.

Perfect for Turbo & Track Builds

This radiator is especially valuable for:

• Turbocharged H22 setups
• Nitrous applications
• Track-focused Preludes
• High-compression builds
• Autocross setups

Improved cooling helps reduce:

• Heat soak
• Temperature spikes
• Thermal fatigue
• Power loss during hard driving

Especially because boosted H-series motors produce enough heat to concern nearby atmospheric conditions.

The Mishimoto performance aluminum radiator features a lightweight dual core, 100 per cent brazed aluminum, and polished end tanks so one can reinforce the overall performance of your engine. Each and every Mishimoto aluminum radiator is a right away OEM fit, making installation effortless and not using a cutting or modification required. All Mishimoto radiators come with a high pressure 1..

Compatible Honda Prelude Models

The Mishimoto Performance Aluminum Radiator is compatible with:

• 1997 Honda Prelude
• 1998 Honda Prelude
• 1999 Honda Prelude
• 2000 Honda Prelude
• 2001 Honda Prelude

Engine compatibility:

• 2.2L H22-powered Prelude models

Perfect for:

• Street builds
• Turbo H22 projects
• Track-day cars
• OEM+ restorations
• High-revving canyon builds
• Daily-driven Hondas

Because no Prelude owner hears VTEC crossover once and decides:
“Yep, stock forever.”

Overall Size: 27.4” x 17.8” x 2.47” / Core Size: 24.45” x 16.85” / Rows: 2
Inlet & Outlet: 1.25”, 1.5” / Core Thickness: 1.97” / Tank Wall Thickness: 0.08”
TIG-welded aluminum radiator includes magnetic drain plug

Better Reliability for Daily Drivers

Even naturally aspirated Prelude builds benefit from:

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

Especially important for:

• High-mileage H22 engines
• Summer-driven cars
• Older cooling systems
• Spirited daily drivers

Because aging Hondas already leak enough emotional stability without adding coolant problems.

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
• Basic socket set
• Hose clamp pliers
• Approximately 1-3 hours

No major:

• Fabrication
• Cutting
• Custom mounting typically required

Which is fortunate, because Prelude engine bays already become crowded the second modifications begin.

Why Upgrade the Honda Prelude Radiator?

Common reasons Prelude owners upgrade radiators include:

• Aging OEM radiator failure
• Turbocharging
• Track overheating concerns
• Preventative maintenance
• Cooling reliability upgrades
• H22 performance modifications

A performance radiator remains one of the smartest upgrades for older Hondas because:

• Heat kills reliability quickly
• High-revving engines create serious thermal load
• Modified H-series engines overwhelm factory cooling systems fast

Especially once VTEC addiction fully develops.

Final Verdict

For 1997-2001 Honda Prelude owners wanting improved cooling performance and long-term reliability, the Mishimoto Performance Aluminum Radiator delivers major thermal management improvements with OEM-style fitment.

Key benefits include:

• Full aluminum construction
• Thick 2-row cooling core
• Improved heat dissipation
• Better cooling stability
• Ideal for turbo and track builds
• Direct-fit installation

Most importantly, your Prelude finally stops treating every VTEC pull like a thermal endurance event.
