Detailed Description

Bosch 5347WS is an engine air filter designed to trap airborne contaminants before they enter the engine. The pleated media increases usable filtration area, while the polyurethane sealing edge helps maintain a consistent fit and reduce bypass at the filter perimeter. This makes it a practical replacement choice for drivers servicing a Ford F-150, Ford F-250 Super Duty, Ford F-350 Super Duty, Ford Expedition, Lincoln Mark LT, or Lincoln Navigator.

This part cross-references Ford 4L3Z9601BA for the same application.
