New Spark Plugs and routine 100k maintenance

[BarnyardHoe04]

My Tahoe recently hit the 100K mark and I'm at that point where I need to change the spark plugs and do some routine things to keep her running for the next 100. Any recommendations on new plug brands? Any routine maintenance tips you have would be nice to make sure she lasts

I used the ac-delco 41-110 spark plugs on my Yukon. They are iridium and seem well recommended. GM says to change the trans fluid at 100k but people debate back and forth over that. I did and it seemed to do good for me. I'm sure more will chime in. People also tend to overlook greasing everything in the steering linkage and such so that's something to check.

Hi,
I am the tech manager at Autolite Spark Plugs. your Tahoe came from the factory with Iridium spark plugs made by either Autolite or NGK. Autolite Iridium plugs cost less and are available at Autozone, Advance, NAPA and many other stores. You can learn about this technology by watching the metalurgy video in the tech section on our website, autolite.com
