ACDelco ACDelco Glow Plug, Duramax | 2001 - 2004

Hard start?

These are OEM Glow Plugs which we feel are the most reliable and not prone to issues that some aftermarket may have such as tip swelling.  

Glow plugs are one of the most important components when trying to start a diesel in cold weather. Worn or in-op glow plugs can cause a hard start or even check engine lights on today's trucks.

Sold Individually

Comes with nut. Fits Federal and CA emission systems.

Be sure to carefully inspect the Glow Plug Bus Bar as well during service, it is common for this to fail between cylinders 6 and 8 on the driver side rear of engine.
