The BALDWIN FILTERS RS3997 is a replacement automotive air filter designed to remove airborne contaminants from the intake air stream before they reach the engine. With an outside diameter of 5-17/32 inches and an overall length of 20-9/16 inches, this filter fits applications where precise dimensional matching is required for proper sealing and airflow. It is installed by automotive and fleet maintenance technicians as part of routine preventive maintenance or whenever intake restriction is detected during service.
This air filter is suited for automotive and light-duty applications requiring a radial-seal or panel-style intake filter of this size class. It is appropriate for use in vehicles and equipment where the RS3997 dimension profile is specified. Technicians working on fleet vehicles, agricultural equipment, or specialty automotive applications will find this filter applicable when OEM-spec dimensions must be matched for housing fitment.
Designed as an OEM-style replacement air filter for automotive and light-duty applications requiring the RS3997 dimensional profile. No additional specific compatible model numbers were provided in the product data.
Air filter replacement is a standard maintenance task performed by automotive and diesel technicians. Before servicing the air filter housing, shut down the engine and allow it to cool. Inspect the filter housing and sealing surfaces for cracks or debris before installing the replacement filter. Ensure the filter is fully seated and the housing cover is secured before returning the equipment to service.
