The Ryco Oil Filter is a direct-fit replacement for 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 100kPa to protect the engine during cold starts and heavy load. The steel canister is roll-formed and pressure tested well beyond normal operating pressure. 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. Thread and gasket dimensions match the factory unit, and a nitrile seal is pre-fitted to the base plate. Filtration efficiency is rated at 5 micron nominal with a high-capacity Cellulose element that holds contaminant without restricting flow. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. Supplied new and backed by a 24 Months warranty.
