Forge PolarCooler Charge Cooler Radiator Upgrade for Audi RS6 & RS7 (C7 Platform)
With modern aftermarket ECU tuning pushing high-performance V8 twin-turbo engines harder than ever before, thermal management is paramount. In demanding driving conditions, your vehicle runs a severe risk of receiving inadequately cooled intake air, which negatively impacts engine efficiency and ultimately causes a substantial loss of power. To address this issue, Forge Motorsport is proud to release the PolarCooler auxiliary cooling system—the premier frontal water cooling solution for the Audi RS6 and RS7 (C7 platform) market. This kit ensures your vehicle maintains peak performance under pressure.

Key Engineering Features
- 100% Extra Capacity: Features a 22 FPI (fins per inch) louvre super-tech cooling core to deliver maximum heat dissipation.
- Innovative Dual-Core Flow: The PolarCooler retains the OEM charge cooler radiator but routes the fluid into a front-mounted auxiliary radiator for maximized efficiency.
- Unobstructed Placement: Positioned carefully to ensure zero obstruction to the air conditioning condenser, preventing thermal bleed-over.
- Proven Dyno Performance: Real-world testing demonstrated a continuous 20°C (68°F) reduction in inlet temperatures across three back-to-back dyno runs.
- Advanced Hose Engineering: Includes high-grade silicone hoses lined with Flurosilicone, safeguarding against modern O.A.T. coolants and oil mist.

Comprehensive Hardware & Fitment Details
The Forge PolarCooler system comes complete with all required hardware, including an OEM-modified structural crash bar and tailored silicone hoses to ensure a seamless installation. The hand-fabricated end tanks and crash bar feature a durable, anti-corrosion black powder coat finish. Handcrafted entirely in Great Britain, this high-end kit includes a worldwide lifetime warranty.
IMPORTANT NOTE: This kit is not compatible with vehicles equipped with factory Nightvision Assist options unless the Nightvision system is permanently removed.
