The rubber bushing gets stuck in the spark plug head making it very difficult to use it to tighten the spark plug without grabbing the rubber bushing. In practice, these sockets can only be used to remove the old spark plug and install a new spark plug in place, but DO NOT tighten. Remove the spark plug head from the hole, then remove the rubber grommet inside the spark plug head, and then tighten the spark plug with the spark plug head. Very cumbersome, just buy a ffs magnetic socket!
