This Wesfil Oil Filter replaces the original equipment unit on Mazda CX-3 and Mazda CX-5 and Mazda3 2.0L Petrol models built from 2016 to 2022. The bypass valve opens at 80kPa to protect the engine during cold starts and heavy load. The steel canister is roll-formed and pressure tested well beyond normal operating pressure. An integrated anti-drainback valve keeps oil in the filter at shutdown, so oil pressure comes up quickly on start-up. Packaging and labelling include the part number and application data for easy stock control. Fitting is a straightforward workshop job and no coding or calibration is needed. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. Every unit is supplied new with a 2 Years / 40,000 km warranty against manufacturing defect.
