My Son's 2013 Chrysler 200, 2.4L with 110,000km + showing on the speedometer.. The Query is the Life of the Spark Plugs.. Car runs like a top and starts right up without any hesitation, this will be the 5th Winter and has never been Plugged In...
Like the Old Saying "If It's Not Broke, Don't Fix It".. But on the Preventive Side I'm saying it may be a Good Idea to have the Plugs changed when car is checked over for Winter.. Thoughts & Opinions Appreciated.. Cheers Thanks

How about the whole TUNE-UP if we are talking prevention?

Newer car with iridium or platinum plugs, 50-120,000 miles. Older cars, standard plugs 30-45,000 miles. Air filter 15-30,000 miles depending on where you live (dusty conditions). Fuel filter typically 30,00 miles but many newer cars don't even mention changing the fuel filter in the service manual. It's supposed to be maintenance free.

Owners manual should tell you. I just changed the plugs on my 05 CRV, 125,000 miles
Still looked perfect
