Engineered for Australian operating conditions, this Ryco Oil Filter suits Isuzu D-Max and Isuzu MU-X and Mazda BT-50 1.9L Turbo Diesel models built from 2021 to 2025. The bypass valve opens at 125kPa to protect the engine during cold starts and heavy load. Change intervals of 10,000km are typical, or every six months for vehicles doing short trips and towing. An integrated anti-drainback valve keeps oil in the filter at shutdown, so oil pressure comes up quickly on start-up. The steel canister is roll-formed and pressure tested well beyond normal operating pressure. Filtration efficiency is rated at 5 micron nominal with a high-capacity Synthetic Media element that holds contaminant without restricting flow. Thread and gasket dimensions match the factory unit, and a nitrile seal is pre-fitted to the base plate. New stock, 24 Months warranty, and dispatched from our Australian warehouse.
