Did you actually change your 453 Spark Plugs @ 30k Miles?
What be your story ?

I did on my 2016 a couple months ago at slightly over 30k. Factory plugs were iridium so they probably could have gone longer. Watched a German guy change out original plugs on his 2016 and they were NOT iridium so should have been replaced.
