I want to change the spark plugs out but have been seeing that spark plugs like to break off inside. There are recommendations to take them off hot, warm or cold which seemingly contradict each other. Lisle makes a tool that can extract them if broken but that does not seem like a great option. Has anyone done this? If so, recommendations?

Not a common problem; generally only happens if you put too much side load on them. You can reduce the chance of that with a 6" or longer socket extension.
