ACDelco GM Genuine Parts 9G Glow Plug (Pack of 1)

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 injector, 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.

Excelente calidad OEM, es de la marca Beru, es el reemplazo perfecto

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.

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.

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.
