Baldwin Filters RS5478-FN Air Filter

The Baldwin Filters RS5478-FN is a new automotive engine outer air filter with a radial design. It serves vehicles that require an element-only filter measuring 7 inches in outside diameter and 16 7/16 inches in height. This part is intended for maintenance or repair of compatible engine air intake systems.

Radial element-only installation

Installation involves placing the radial filter element into the existing air cleaner housing. Because the unit is an element-only design, no additional framing or sealing components are included. The most common issue occurs when the housing dimensions or sealing surfaces do not match the filter's 7-inch diameter and 16 7/16-inch height, preventing a proper seal.

Verify housing dimensions and compatibility

Before ordering, confirm that your air cleaner housing accepts a radial element with a 7-inch outside diameter and a height of 16 7/16 inches. Check the housing sealing surfaces for damage or distortion that could allow unfiltered air bypass. Ensure the application does not require a framed filter assembly, as this product is an element only.
