2015 Suburban..tune up time

[camperhead]

Ive got a 15 with 130K. Tune up time..... Whats everyones thoughts on spark plugs. Currently Rock auto is out of ACDELCO 41114, they have NGK 4344 and couple different Denso's. I have ran NGK in my older gen 5.3 no problem....... Thoughts in this gen 5.3?

I am replacing plug wires too planning on using ACDELCO 758EE

i run ngk in everything anymore. i dont have a 5.3 but i run them in my 5.7 in my 97. an 08 civic an 07 pontiac 3.5 a 13 accord and my bike. just buy the ngk reccomended or the more expensive ngk. i havnt messed with any of the new ruthenium plugs yet. after iridium ruthenium just seems like smoke and mirrors to get more money.

I would stick with what it was born with. Head down to the GM dealer and buy 8 plugs.
