“Avoid spark plug removal while the engine is hot. Since the cylinder head spark plug threads are aluminum, the spark plug becomes tight due to the different coefficients of heat expansion.
Can you replace spark plugs on a warm engine?

This can lead to a plug that is too loose or too tight depending on the application.
