Front Mount Heat Exchanger – Mercedes 45 AMG Cooling Upgrade

Built for CLA45 & GLA45 AMG Owners Who Demand Track-Ready Cooling

Your CLA45 or GLA45 AMG runs hot under pressure—but it doesn’t have to. This high-capacity front mount heat exchanger delivers superior cooling performance under high-boost conditions, track use, and aggressive street driving. It’s the cooling mod serious 45 AMG owners start with for real-world horsepower and long-term reliability.

🔧 Key Performance Features

• Optimized Cooling Core: Larger surface area and improved coolant flow reduce intake temps and fight heat soak
• Direct Bolt-On Fit: No cutting, no custom fab. Drops into place with OEM lines and brackets
• Durable Construction: TIG-welded aluminum core handles high-pressure/high-temp conditions
• Aggressive Driving Ready: Designed for high-load use—spirited canyon runs, summer heat, and track days
• Horsepower Gains: Cooler IATs = stronger pulls and consistent power under full throttle

💥 Why It Matters for CLA45 / GLA45 AMG

The factory heat exchanger on 45 AMGs can’t keep up with performance mods, summer heat, or extended pulls. With this upgrade:

• You’ll run cooler IATs under boost—protecting power and engine life
• Enjoy stronger mid-range power during back-to-back pulls
• Experience faster recovery between shifts and laps
