These premium aftermarket replacement spark plugs are manufactured to meet or exceed your expectations for fit, form, and function.

Review: 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.

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.
