Engineered for Australian operating conditions, this Audi Genuine Air Filter suits Audi A4 2.0L Turbo Petrol models built from 2017 to 2023. Pleat count and depth are matched to the factory element so induction noise and airflow stay standard. Service life of around 30,000km applies in normal conditions; halve that for dusty and rural use. The Cellulose media traps fine dust without choking airflow, which matters on Australian gravel and unsealed roads. The frame is fully sealed at the corners to stop unfiltered air bypassing the element. Restriction is measured at under 80kPa at rated engine airflow. Panel dimensions are approximately 310mm x 200mm, with a moulded polyurethane frame that seals hard against the airbox. New stock, 24 Months warranty, and dispatched from our Australian warehouse.
