Engineered for Australian operating conditions, this Wesfil Cabin Pollen Filter suits Audi A4 and Audi Q5 and Volkswagen Golf models built from 2018 to 2020. The frame is treated to resist mould and bacterial growth in humid conditions. The Activated Carbon media captures pollen, road dust and brake particulate down to 20 micron. Element size is approximately 200mm x 95mm and slides into the factory housing behind the glovebox. Replacing this filter every 20,000km restores air conditioning airflow and reduces musty smells at start-up. An activated carbon layer reduces exhaust odour and diesel fumes in traffic. We recommend fitting by a qualified technician and following the manufacturer's torque specifications. Supplied new and backed by a 12 Months warranty.
