went down to sss performance not far from me today to get my iridium plugs and splitfires, decided to fit them while i was down there and look what happened! went to undo no.1 plug and the thing sheered off with no efford at all leaving a stub in my head with nothing to lock onto it too undo it. thanks to one of the workers he managed to use a drill, chisle, hammer, 14mm spanner, some elbow grease and a hoover and 30mins later it was out!!! how lucky was i, thourght ye old head was going to have to come off!!!!
