The Wesfil Air Filter is a direct-fit replacement for Mazda BT-50 3.2L Turbo Diesel models built from 2016 to 2019. The Cellulose media traps fine dust without choking airflow, which matters on Australian gravel and unsealed roads. Pleat count and depth are matched to the factory element so induction noise and airflow stay standard. Restriction is measured at under 120kPa at rated engine airflow. Service life of around 30,000km applies in normal conditions; halve that for dusty and rural use. Panel dimensions are approximately 330mm x 140mm, with a moulded polyurethane frame that seals hard against the airbox. The frame is fully sealed at the corners to stop unfiltered air bypassing the element. Every unit is supplied new with a 2 Years / 40,000 km warranty against manufacturing defect.
