Charge Cooler Radiator for the Audi RS6 C7 and Audi RS7

🔥 Summary

The Forge Motorsport PolarCooler is the first dedicated auxiliary charge cooler radiator system developed specifically for the C7 Audi RS6 and RS7. It’s designed to solve a common issue in tuned 4.0 TFSI engines—rising intake air temperatures (IATs) under aggressive ECU tuning and repeated hard driving.

🚀 Key Highlights

1️⃣ Over 100% Increased Cooling Capacity

• Uses a 22 FPI louvre super-tech cooling core
• Dramatically improves heat dissipation efficiency

2️⃣ Intelligent Auxiliary Design

• Retains the OEM charge cooler radiator
• Adds a front-mounted auxiliary radiator
• Positioned to avoid condenser obstruction
• Not stacked directly in front of the main coolant radiator
• Installed last in sequence for optimal airflow efficiency

3️⃣ Proven Temperature Reduction

• Achieved 20°C (68°F) lower inlet temperatures
• Tested across 3 consecutive dyno runs

4️⃣ OEM System Integration

• Keeps factory bleed point
• No additional header tank required
• Works with OEM one-way pressure valve system

5️⃣ Premium Fluorosilicone Hoses

• Inner liner compatible with:
  
• OAT (Organic Acid Technology) coolants
• Long-life coolants
• Oil mist resistance
• Stronger than OEM hoses
• Improved durability and engine bay aesthetics

6️⃣ Complete Installation Kit

• Includes OEM-modified crash bar
• Hand-fabricated end tanks
• Anti-corrosion black powder coating
• All required hardware included

🎯 Why It Matters

For tuned RS6/RS7 builds (Stage 1–3), maintaining low intake temperatures is critical for:

• Consistent power delivery
• Reduced heat soak
• Engine reliability
• Sustained performance in hot climates (especially relevant in Malaysia’s weather 🌡️)

The PolarCooler isn’t just a larger radiator—it’s a properly engineered cooling strategy upgrade for serious power builds.
