Wagner Tuning Audi RS4 B9/RS5 F5 Radiator Kit

This is the Wagner Tuning high-performance radiator kit specifically for the Audi RS4 B9 and RS5 F5 models. If you're pushing your high-performance Audi hard, especially on the track or in demanding street conditions, keeping engine temperatures in check is crucial for both performance and longevity. This radiator is designed to handle the increased heat load that comes with a powerful engine, helping to prevent overheating and maintain consistent power output.

Wagner Tuning builds these radiators with a focus on efficient heat dissipation. They use a larger core with more surface area and optimized fin design to help air flow through and transfer heat away from the coolant more effectively than the stock unit. The end tanks are typically constructed from cast aluminum, offering a solid mounting point and good flow characteristics. This well-built unit is a direct replacement for your factory radiator, meaning it's designed to fit right into your existing cooling system setup without major modifications, though some minor adjustments might be needed during installation. It's a substantial upgrade for anyone serious about managing their engine's temperature under stress.

When installing this radiator, it's a good idea to inspect your coolant hoses and thermostat for any signs of wear, as this is a prime opportunity to replace those components if needed. Ensure you use the correct type of coolant specified for your Audi to maintain optimal performance and corrosion protection. This kit is a solid choice for RS4 B9 and RS5 F5 owners looking for improved cooling capacity.
