I was told by a dealer that Harley Davidson spark plugs are manufactured by Champion, and that they were junk. Is this true? I guess that should be of no supprise after reading about Harley Davidson oil.
There is nothing wrong with the Champion plug but if you feel better changing them then do it. Harley have been using Champions for 37 years that I know of without problems.

I agree but I think it's been longer than 37 years...but what do I know?
