420807945A Audi AIR DUCT

This part basically channels airflow. It directs air coming in through your grille towards things like the radiator, the intercooler if you’ve got one, and even the brakes to keep them cool. It's not just an open space; the duct shapes and focuses the air where it needs to go. Sometimes it also has little flaps or vanes inside to fine – tune that airflow. Think of it as part of your car’s cooling system, but for the front end. It sits right behind the grille and works with the radiator and cooling fan to manage engine temperature. It's not something structural, meaning it doesn’t hold anything together, it's entirely about moving air. It also helps keep debris like leaves and bugs from getting directly into sensitive components. If this duct is damaged or missing, your engine can overheat, especially in stop – and – go traffic or hot weather. It’s one of those parts that, when it’s working right, you don't even think about it. But you’ll notice if it’s cracked or broken; your temperature gauge might start running higher than normal, or the engine might feel sluggish. It acts like a shield, protecting key parts and keeping things running efficiently. You can find replacements pretty easily, and places like Fixparts Online usually have them in stock. Getting a new one if yours is damaged is a good way to prevent bigger, more expensive problems down the road. Your assurance of quality: Air Duct (MPN 420807945A) comes with a 12-month warranty!
