What happens if spark plugs aren’t tight enough?

A spark plug that’s too loose can also be problematic. Not only can under-tightening cause damage to the spark plug, but it can also lead to pre-ignition and potential engine damage. The loose spark plug may also blow out of the spark plug hole, causing damage to the engine’s cylinder head.

What happens if you under torque spark plugs?

In most cases of under-torque, the vibrations inside the spark plug cause the ground electrode to break down, causing serious damage to the part. This restricts the ability to transfer heat to the shell and cylinder head, causing the insulator nose to overheat and starting pre-ignition.
