Never use a standard 16 mm deep socket. it provides no protection for the ceramic part of the spark plug if your not located on it squarely. They can easily snap off and you know how deep down they are. Don't use one of those crap all-in-one socket/handle wobbley ones either. Get yourself a good quality purpose made spark plug socket with a rubber insert. You can get one here----> http://www.auto-tools.co.uk/s.php?p=6864
