Another question - for sparks plug. The manual says replace 30k 60k and so on, but is the necessary?

Since the NGK spark plugs that is recommended in the Civic 2017 ex-t (the car i drive) claims the spark plugs runs for 100k miles.
I haven't change my spark plug yet, my car just reached ~36K miles so it is still the original spark plugs that is in the car.

What is everyone else take on this?

This is my first car so I'm very clueless and the mechanics in my area says to change it at 30k, some said 20k and some say don't worry about it until 50K... it is extreme mix message.

Is your car tuned? If its just a regular dd style car with no mods, just stick with the regular 100k mile change unless you see an issue such as misfire or something like a significant mpg drop without any reason.
