About
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.

Best replacement for OEM plugs

Blitz

in 10 days

Had OEM plugs fail ( insulator failure), after talking with counter person. We both agreed there was no better choice then the NGK Laser Iridium Plugs. My 2000 GMC Sierra 5.3, is performing better than ever.

I had one spark plug go bad so replaced all 8. Shows these will not fit but they are what should go in my 2000 GMC Sierra truck. When my truck came out they only had platinum plugs. These Iridium’s came out later and bulletin was changed to these being replacement. I can instantly tell the improvements of these over stock.

No need for expensive plugs. These work great!

It was a pain in the butt to just get plug wires off then ridiculous to get to the rear 3rd plug on left side on my 2003 GMC Sierra pickup v6. And wasn’t easiest to get a couple plugs back in. None of this was the plugs fault, they work great. Still had miss and check engine light coming on so I changed plug wires also. Problem fixed.
