Wagner Tuning Audi S4 B9/S5 F5 US-Model Competition Intercooler Kit

This is the Wagner Tuning Competition Intercooler Kit for your Audi S4 B9 or S5 F5 US-Model. If you're looking to get the most out of your turbocharged engine, especially if you've made other performance upgrades, a larger, more efficient intercooler is a critical component. It helps cool the compressed air coming from your turbochargers before it enters the engine. Cooler air is denser, meaning more oxygen can be packed into the cylinders, which directly translates to more power and better throttle response.

Wagner Tuning built this kit with a focus on maximum cooling performance. It features a large, high-density bar-and-plate core that offers significantly more surface area and volume than the stock intercooler. This means it can absorb and dissipate heat much more effectively, even under demanding conditions or after multiple pulls. The kit includes custom-fit aluminum end tanks that are designed to optimize airflow into and out of the core, ensuring that every bit of that cooling surface is put to work. Everything is designed to fit right into your S4 or S5, replacing the factory unit without major fabrication.

This kit is a popular choice for enthusiasts looking to push their B9/F5 S4 or S5 platforms further. It's designed to handle increased boost pressures and higher intake air temperatures that come with engine tuning and other modifications. While it's a direct replacement for the stock intercooler, it's important to note that this kit is not CARB approved and cannot be shipped to California. For optimal performance, consider pairing this with other engine management and intake upgrades.
