Ford Motorcraft Glow Plug for Ford (2004.5-07) F-250/350/450/550, (04.5-05) Excursion & (04.5-10) E-350/450, 6.0L Power Stroke (build date after 1/15/04)

This is the genuine Ford Motorcraft glow plug, part number 4C3Z-12A342-A, for the 2004.5-2010 6.0L Power Stroke. It fits 2004.5-07 F-250, F-350, F-450 and F-550 Super Duty trucks, 2004.5-05 Excursions and 2004.5-10 E-350/E-450 vans.

A 6.0L with tired glow plugs cranks longer and idles rough with white smoke until it warms up, and it gets worse every cold snap. On high-mile work trucks, vans and Excursions, a fresh set is one of the cheapest ways to get normal cold starts back.

We also recommend replacing the under-valve-cover harness when you do glow plugs on a 6.0L. The covers are already off, and a brittle or cracked harness connector will kill a new plug just as fast as a bad plug.

Check the build date on the door tag before ordering. 6.0L engines built before 1/15/04 use a different glow plug. Install on a cold engine and torque to Ford spec.
