Question on AC Delco plugs

[Rayyy]

Which spark plugs do you use?

Anyone know the part number for Iridium AC Delco plugs?

This is going into a 2001 Yukon XL 5.3 4x4

Any thoughts on the NGK TR5IX (7397) Iridium plugs or the NGK Laser Iridium (1465) plugs?

41-110 are the AC Delco factory spec. There's a rebate on them now. I paid $48 for 8 and am getting $24 back. Not bad.

I like the AC Delco plugs. I used the iridium in my 2010, but the cheaper platinums on my older truck.

Why does the O’Reilly website say that the 41-110 plugs don’t fit the 2001 Yukon 5.3?

Could it be that the original spec was for a .060" gap and they haven't corrected their information?

The current ACDelco Iridium Spark Plug number is 41-162.

Well, according to the O’Reilly website, the 41-162 plugs also do not fit the 5.3 engine.

Are we sure it isnt 41-962

They're wrong.

That's a Platinum number, the other is for Iridium.

Ray, plug your VIN in here and have a look: https://parts-catalog.acdelco.com/catalog/catalog_search.php
