Notably, some vehicles like the Toyota Highlander you can’t even figure out when you need to change the spark plugs, let alone what kind of spark plugs you need from the owners manual.
Theoretically, they are to be replaced at 120k miles (!!) but they won’t even tell you that in the owners manual.

Insane.
