Replacement glow plugs.
Slightly different ratings then what I pulled out. But they work.

Perfect fit (2016 Duramax)
Perfect fit because they are OEM. Saved a ton of money by installing myself. Watched a lot of YouTube horror stories on the process, but in the end it wasn’t bad. Took my time, applied gentle pressure, and the original glow plugs came out easily.

Made in India?
Package looks OEM (ACDelco) and states made in Germany, part stamped wth made in "India". Hopefully will last as long as OEM. One star off for made in different country than advertised.

Get the proper GM part for your diesel
Fixed my check engine light. Not an easy replacement on the drivers side of my LMM, even with the tire off and wheel well removed. Get 4mm nuts before you start as existing will most likely be rusted.
