• Description:

  This is a genuine Ford OEM glow plug for the 6.4L Power Stroke turbo diesel V8, cataloged by Ford under Spark Plugs and Glow Plugs with the ZD-15 engineering reference. It threads into the cylinder head to preheat the combustion pre-chamber, providing the heat needed for reliable cold-weather starting and smooth diesel ignition before the engine reaches operating temperature. It fits 2008 through 2010 Ford F-250, F-350, F-450 and F-550 Super Duty trucks equipped with the 6.4L twin-turbo diesel engine, with one glow plug serving each cylinder. Buyers typically replace glow plugs when they experience hard or extended cranking on cold mornings, rough running and white smoke immediately after a cold start, an illuminated glow-plug or wait-to-start light, or a stored glow-plug circuit fault code pointing to an open or shorted plug. Because the plugs share the same duty cycle, a technician servicing one weak plug often renews the full bank to restore consistent starting. This part matches the original factory heat range, tip design, and thread pitch so it seats correctly and maintains proper reach into the pre-chamber. Torque the plug to the Ford-specified value and use care when threading into the aluminum head to avoid cross-threading or seizing. Confirm your build against the 8C3Z-12A342 base before ordering, as the 6.4L uses a distinct plug from the earlier 6.0L Power Stroke engine.
