Shipping package should be a box instead of a bag
Fast shipping, arrived as described. I would encourage shipping in a box rather than a bag because several of the individual boxes we smashed

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.
