I agree with Ron on the wires but would run the 41-985 or 41-110 or 41-162 Iridium spark plugs. The first two part numbers have been superceded to the 3rd. The first was original equipment.

amazon shows that those wires don’t fit my vehicle

I have had good luck with these.

I looked them up at RA and the 6.2 and the 5.3 2007 Yukon took the same wires. Even calls for the same wires for a 6.0 engine.

When I check the vehicle application at Amazon it does say that the wires do not fit but the number came from RA and then I crossed it at Amazon.

At GM Parts Giant the set calls for 19351593 and when you cross that it goes to 748RR.

ACDelco 9744RR wires
I cleaned, gapped(.040"), and reinstalled my old 41-985 plugs. I have a new set of 41-962 plugs on the shelf for whenever.

 

[avalonandl]

you want the AC Delco Iridium plugs. Stay away from Bosch plugs.

 

[14RamHemiSport]

lots of warnings of counterfeit plugs on amazon. be cautious. Personally id stick to rockauto.

 

[avalonandl]

Counterfeit or OLD STOCK plugs are sold on some of the Amazon and ebay sites.

What mileage are you all normally changing? I'm just coming up on 80K and was thinking to go ahead and change both.

 

[gooffeyguy]

Pretty sure maintenance schedule says 100k.

I've gone till about 110k before changing on my 2001, and 105k on my 2012

Go ahead and do it. Mine were 7 years old and 134k on them.

My highway gas mileage went up as did performance. The old plugs were missing at high rpm.....which I rarely did since this is a 6000 lb SUV. Not like my 2017 Camaro SS.....

Another vote for getting these parts from Rock auto, unless you are in a hurry. I have wires, plugs and exhaust manifold bolts (6.2 motor) waiting to get installed once the weather starts to cooperate a bit more.

Rock Auto won't ship to my house now. I live in an incorporated town in Colorado, and they refuse to calculate and account for the town tax (if there even is any) that I would have to pay. If I order from them, it's because it's too good of a deal compared to other vendors, and I have to have it shipped to my son's place, which is in an unincorporated area. And somewhat inconvenient.

So typically I use a vendor that really wants my business and is willing.

I hate this every time you mention it. It sucks and is beyond reason. However, I'm pointing at your government, not the business. 50 states is more than enough jurisdictions to be registered as a business and keep track of collecting taxes for. Bummer for all involved.

120 K on mine and actually they looked good, might have gone another 20 k. Used RA, Iridiums 41-162 and the Delphi/Delco red wires listed, fit perfectly and look a bit cool as well.

 

[gooffeyguy]

And add 10hp cuz they're red

Anything red adds hp

Sorry if this sounds like a dumb question, but how bad of a job is it to change the plugs? I've held off because of a fear of snapping them off, but it is time that I take care of them (possibly the factory plugs, 145K).
