When do you typically change spark plugs?

Who reads the books? Joking aside replace the spark plugs anyway it wont hurt anything and may improve fuel mileage and running conditions at this point. If you take a video of the noises you hear, post it online and we might be able to help.

They are so cheap and easy to change....my 2018 says 40K. I'm tuned blah blah blah so it's a few times a year b/c ignition/misfires seem to be a thing with these once you monkey with them and again....it's 30 min and a few bucks.

Everything will be close enough to the same.
True yeah as I said i did read what you guys suggested but are spark plugs that important to change every so often like that guy that suggested every 10 to 15 k miles? I mean i can run a video too of how my car sounds upon starting does that help with me needing new ones yet or?

Here is what my booklet looks like I have attached photos. The only time it mentioned replace plugs was way up to 120, 000 km and intervals before that nothing. Maybe in the states its different vs what they offer here as a revised Canadian version of maintenance of same vehicles no idea.
