Wagner Tuning Audi RS4 B9 2.9 TFSI Radiator Kit

This kit includes the Wagner Tuning high-performance radiator specifically designed for the Audi RS4 B9 with the 2.9 TFSI engine. It's a direct replacement for your factory unit, meaning it fits right into the existing mounting points without needing modifications. This radiator is built to handle the increased cooling demands that come with a performance-oriented vehicle like the RS4 B9, especially if you've made other engine upgrades.

Wagner Tuning uses a well-built, multi-core design for this radiator. The core features a higher fin density and larger surface area compared to the stock radiator. This setup allows for significantly improved heat dissipation, which is crucial for maintaining optimal engine temperatures under hard driving or track conditions. The end tanks are constructed from aluminum, offering a solid and lightweight solution that also resists corrosion. By keeping your engine cooler, this radiator helps prevent heat soak and can contribute to more consistent power output.

When installing this radiator, you'll want to have the necessary coolant and potentially new hose clamps on hand, as it's a good opportunity to replace any aging components. Refer to the manufacturer's installation instructions for specific details regarding coolant fill and bleeding procedures to ensure proper operation. This radiator is a solid choice for RS4 B9 owners looking to enhance their vehicle's cooling system for improved reliability and performance.
