GMC Sierra Spark Plug

Since your GMC Sierra is designed for top-notch strength and performance, your engine components should be as well. A GMC Sierra spark plug has a big role to play in your vehicle. By using a ceramic insert, a high-quality spark plug ensures that it sparks at the tip of the electrode and nowhere else. When it's time for a durable upgrade, AutoZone has you covered.

Treating your truck right is the only way to guarantee you get many years' worth of work out of it. Spark plugs for GMC Sierra are made to manufacturer's standards, which often times dictate that a vehicle use a hot plug with a smaller ceramic insert than normal plugs. Speak with the friendly staff at your local AutoZone to find the best product for your truck and get your battery charged and engine tested for free while you're shopping our extensive selection.

      Just swapped the old original 41-993s they had 209,000 miles they were still serviceable with normal wear. Good to go back with original ACDelcos.
