2011-2012 F-Super Duty

This article supersedes TSB 11-5-14 to update the vehicle model years, Issue Statement and Service Procedure.


Some 2011-2012 F-Super Duty vehicles equipped with a 6.7L engine may experience a loss of power due to engine air cleaner (ACL) snow packing when operated in extreme snow conditions or when equipped with a snow plow. This concern may result in diagnostic trouble codes (DTCs) P0299 and/or P1247. A low restriction secondary foam filter is now available to resolve this concern.
