Part # OEM Spark plugs for C6 LS3 2012 Base?
Lots of post about this and no one gives a straight answer.
Plp start giving recommendations... use XX or XXX.
​​​​​​Others say I installed XXXX and they work well.
Not interested in any of the XXX options available out there, just the OEM please.
AC Delco web page says 748UU
Dealer told me on the phone 9748UU
Which one is it?
Also, do they come with the heat shield or do I have to reuse the ones that came with the car?
Thank you!!!

Rock Auto has these for 2012. ACDelco plugs #41-162. $6.16 each...Wire Set ACDelco #9748UU is the Premium Pro/Gold $35.79. Dont know what makes them premium vs standard.. #748UU is the base OEM standard version. Yes the shields are reusable. Its a simple metal tube that slides on & off over boot. Not included with new wires. No need for new ones unless you want to.
I just did my 2008 LS3 with same plug # but different wire set #. Difference being mine were right angle boots where as 2012 are straight. ACDELCO 9748UU
$3.00 per plug rebate from ACDelco link

iridium plugs ARE the superior plug.
