Denso Oil Filter to suit Audi A4 and Audi Q5 and Volkswagen Golf 2.0L Turbo Diesel models built from 2017 to 2025, supplied ready to fit with no modification required. Filtration efficiency is rated at 5 micron nominal with a high-capacity Synthetic Media element that holds contaminant without restricting flow. An integrated anti-drainback valve keeps oil in the filter at shutdown, so oil pressure comes up quickly on start-up. The bypass valve opens at 90kPa to protect the engine during cold starts and heavy load. Change intervals of 15,000km are typical, or every six months for vehicles doing short trips and towing. New stock, 12 Months warranty, and dispatched from our Australian warehouse.
