Best replacement for OEM plugs

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.

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.
