Actually, I wanted to double check before responding, but my SAAB does, in fact, have NGK plugs, which were replaced at the time of the last cassette change (although I don't think they were the time before that). Some of my reading on this subject has indicated that heat and vibration can expedite a cassette failure. I have a slightly bent wheel that causes some vibration at speeds between 55 and 65 mph and my water pump was also failing (not to mention, I live in Florida which is a bit hot during the summer). Has anyone else had an experience where this type of heat and vibration contributed to the failure or am I just coming up with a "post hoc ergo proctor hoc" excuse?
