get a proper size spark plug socket...this is delicate business...you'd KNOW if the spark plug threads are stripped by feel~...okay spark plug sockets have a rubber foamy type dealiebob to hold the nose of the plug...so it won't slip and the ceramic shatter on the concrete~ make sure that you use a PROPER size spark plug socket....also there is a "crush gasket" that once it is crushed will have done the job...no more tightening is needed~ don't warm the engine unless you want burnt fingers on the manifold~

Thank you for the reply. I have a 5/8 "spark plug socket" of course that is way too big for this car, so it's of no use. I'll check the auto parts stores for a 14mm or 9/16 spark plug socket. If I cannot find a spark plug socket for this size of spark plug, wouldn't a strong magnet do the trick to pull out the plug in the engine once it's loosened... good luck to me on loosening it, maybe i'll find a socket that fits these plugs more securely.

there are the two sparkplug sizes...you've obviously got the smaller size...if there's junk in there (oil from the head) take a little brake cleaner on a soft cloth to get that out of there~
