2000 GMC Sierra 1500 what ACDelco Iridium Plugs?

[Mr. Z71]

For what it's worth, at one time the 41-110 was listed for the older applications but changed to the 41-962 based on cost to keep ACDelco competitive. Either plug will work.

So thats why they don't show for my truck even though they work for it.  Thanks for sharing this.  Makes sense now.

I figure it's because since iridium is good for around 100k on wear. For a plug change on a high mileage/20 year old vehicle they probably are thinking Platinum or Double Plats are a better way to go. Cheaper also. I'm sure many people won't opt for the higher $ plug. Plus don't forget prior to 2004, iirc, Iridium as not OE. That being said, most catalogs don't show iridium as an option for my 2004 even though they were OE. They push the Plats.

You were right check the post after yours,  Makes sense.  Regardless the price difference for me between the double plat's and iridium I will no doubt go with the Iridium's.  Thanks for your information
