well i dont quite understand how a spark plug can break ----only alot of force can break it so if there tight why keep pushing till they break ---a bit of spray back and forth motion and some patence should get them out ---i see it as a spark plug and a aluminum head which is always a problem the only spark plugs i ever have problems with is from people cross threading them ----why is this desighn different from other engines
