The Wagner Tuning Competition intercooler kit for 2009–2016 Audi A4 B8 Allroad 2.0 TDI replaces the factory charge-air cooler with a higher-capacity unit aimed at supporting sustained boost. It reduces intake temperatures to help maintain consistent turbo response during demanding driving and is suited for street and track use where cooler charge air improves engine stability.
