Baldwin Filters PA31004 Automotive Air Filter

Product Description

The BALDWIN FILTERS PA31004 is a direct-replacement automotive air filter designed to protect internal combustion engines from airborne contaminants. It filters incoming air before it enters the intake system, helping maintain proper air-to-fuel ratios and protecting engine components from dust, debris, and particulate matter. Installers working on fleet vehicles, commercial trucks, and heavy equipment will find this filter suited for maintenance intervals where OEM-quality filtration is required. At 5.2 pounds, the unit is a substantial filter assembly appropriate for larger engine applications.

This air filter is intended for automotive and commercial vehicle applications where engine air filtration is a routine service item. It is typically installed during scheduled preventive maintenance by fleet mechanics and diesel technicians. The PA31004 is a recognized cross-reference replacement for the Fleetguard AF55020, making it a direct swap in any application where that filter is currently specified.

Power down the vehicle and allow the engine to cool before servicing the air intake housing. Remove the old filter, inspect the housing and sealing surfaces for debris or damage, and seat the new filter fully before securing the housing cover. Follow the vehicle manufacturer's recommended service intervals and any applicable shop safety procedures.
