Spark plugs

[kaiserwillie]

I have a 2016 Yukon SLT that I purchased brand new. I only have 51k in miles on it. I still have the factory plugs and wires on her. Given their age should I think about replacing them?

I'm doing my front brakes this weekend and will pull a couple plugs to see how they look from each side. Thanks...

Because of age only on the wires, I would replace them. While they are off, do the plugs too, but that is me.

Spark Plugs do not wear out with time only miles, same for the wires. Save the money and change them together in another 50,000 miles. I have a 2016 also with 101,000 and I just changed my plugs and wires and I believe I could have gone another 40,000 miles easy. And the rear plug on the passenger side is a bi*ch to get out.
