What happens if you over tighten a spark plug
I’ve had trouble with loose spark plugs in the past, and want to make sure the new ones I’m getting stay on tight—but I’m not sure how tight is too tight. What happens if I over-tighten my spark plugs?

It makes sense to think that tightening your spark plugs as much as possible is the best way to prevent them from coming loose—but there’s such a thing as too much. Simply put, over-tightening your spark plug can cause damage to the wire. Specifically, it can damage your spark plug thread, which means you’ll have to replace the spark plug wire repeatedly.
To avoid this, learn the torque recommendations for your vehicle, as suggested by the manufacturer. Your owner’s manual will outline the torque requirements for changing and tightening your spark plugs!
It’s important to know how you can protect your car from unnecessary harm, like damaged spark plugs—but for situations beyond your control, you’ll need car insurance! Luckily,
