2003-2004.25 6.0L Powerstroke Glow Plug
[GP540]

This glow plug is used in the 2003-2004.25 Ford 6.0L Powerstroke engines below engine S/N 6155637. It is 1.2mm longer than the later 6.0L Powerstrokes. It uses dual coil technology. With the design incorporating a "regulating coil" it is almost impossible to burn out this glow plug. It heats up faster and lasts longer. Because it lights up so fast, the vehicle starts faster, runs smoother, and performs better after start up.
