  • 6.4L AIR INDUCTION SYSTEM RESTRICTION – SNOW – BUILT ON OR BEFORE 3/16/2009
Publication Date: March 19, 2009

FORD:
2008-2009 F-Super Duty

This article supersedes TSB 9-4-7 to add a production fix date.

ISSUE:

Some 2008-2009 6.4L F-Super Duty vehicles built on or before 3/16/2009 may experience a lack of power during acceleration and perhaps the illumination of the check air filter message in the instrument cluster message center. The lack of power condition may occur when the air filter element becomes packed with snow, thereby restricting required air flow to the engine.
