What is the correct AC Delco spark plug for 2016 Suburban?

I see 41-162 41-168 and 41-114 depending on which website I visit. A bit confusing. Looking to replace with iridium AC Delco plugs. Thanks for any info here.

Pull out the easiest one to get to and see what is in your motor as even the AC site has several ones listed.
