Wagner Tuning 17-25 Audi A4 B9 3.0TDI Competition Intercooler Kit

This is the Wagner Tuning Competition Intercooler Kit specifically for the 2017-2025 Audi A4 B9 equipped with the 3.0TDI engine. If you're looking to get more out of your diesel engine, especially if you've modified it for increased boost or are planning to, a more efficient intercooler is a critical component. It works by cooling the compressed air from the turbocharger before it enters the engine, making the air denser. Denser air means more oxygen, which allows for more fuel to be burned, resulting in a stronger, more consistent power output, particularly under sustained load.

Wagner Tuning has built this kit with a focus on performance. It features a large, high-performance core that offers significantly more surface area and volume compared to the stock intercooler. This allows for much better heat dissipation, meaning the air charge stays cooler even when the engine is working hard. The kit includes custom-fit aluminum piping and all the necessary mounting hardware for a direct installation. The internal structure of the intercooler core is designed to minimize backpressure, ensuring that the turbocharger doesn't have to work harder than it needs to, which can help maintain turbo longevity and responsiveness.

Because this kit is designed for competition use and offers a substantial improvement over the factory unit, it's important to note that it is not CARB approved and cannot be shipped to California. This intercooler is a solid choice for anyone pushing their 3.0TDI engine beyond its original specifications and seeking improved performance and reliability under demanding conditions.
