Good value, quailty product...
5 years in on 4 each replacements, no failures. Box marked as made in Germany (Bosch)

All good!
I've replaced two of eight so far (235k miles) with glow plugs from this seller. Ships in OEM box, identical to the ones removed. Both are working fine. Just ordered two more to have on-hand. 2015 2500HD Silverado LML Duramax. Generally easy fix if you remove the inner fender well. Most are very easy access but #8 was tight quarters. Not bad with a 3/8" swivel and/or flex driver. You'll need a 10mm deep socket for the glow plug, 8mm socket for the nut, and a scan tool of some sort to turn the CEL off after replacement. Don't drop that little nut. ~Hour job.

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.

Quality matters when it comes to our GM trucks!
Back in July, #8 glow plug died so I replaced with an ac delco 9G and has not failed since ! This week, the opposite side #7. I can see the pattern here , so I ordered an extra for the shelf in "waiting!" One will argue why not change them all at once?? My truck has 447.000 km so obviously, parts wear & fail. Also, I like to pull my inner fenders I get to inspect so much more in doing so. Anyway, AC DELCO 9G glow plug for me is my # 1 choice for my truck.
