2017 Suburban spark plugs.
I replaced the original ACDelco spark plugs on my 2017 Suburban 5.3L with these Autolites. I went with these because ACDelco is having problems with counterfeits that are coming out of China and being sold as originals. The Autolites came gapped at .050 and I regapped with special tool to .040. 4 days after install, the Suburban is running great and no misfires or codes. The install took me 4 hours in order to make sure I didn’t have to replace my spark plug wires or damage anything else.

Great spark plugs
As a retired professional mechanic I can tell you I trust AutoLite. They are great spark plugs and this iridium will last the life of the engine most likely.

These spark plugs caused a miss-fire. Do not buy.
These spark plugs do not work. At least this particular batch was very poor quality.The engine started miss-firing immediately. I tried to save money by purchasing these but ended up purchasing and installing the original OEM spec AC Delco spark plugs. The miss-fires stopped immediately and the engine returned to normal. I would recommend staying away from these poor quality spark plugs and purchase the recommended OEM replacement spark plugs.

These do not fit what I ordered them for and sadly I waited over a month to try to install them so I can't return

Great Plugs, great price
Iridium plugs are much more expensive than regular plugs and even Platnum plugs. They are well worth the extra money because they last so much longer. Their extremely long life (100,000 miles on my 2016 Siverado) means dollar per mile they are a good value. It used to be that NGK and Denso were the only ones who made them. Autolite has always made high quality plugs and these are no different. It's nice to give the other companies a little competition.
