I bought this champion spark plug on eBay a few weeks ago. The first thing that struck me as odd when I pulled it out of the box was that the finish on it seemed to be very low quality, as the zinc was blotchy like it had been exposed to humidity for a long time. Then when I installed it it there was no spark.
I looked closer at the plug and it seems that some of the metal stamping is less then uniform and the ink, or whatever is used to write the word champion on the porcelain appears to be inconsistent as well.
So I very politely contacted the seller and asked if there was a possibility that this may not be a genuine Champion spark plug. He responded asking if I was accusing him of selling a falsely label product and said that I should return it to him for refund. I think instead I am going to try to contact champion USA tomorrow and see if they would be interested in taking a look at it. Have any of you guys ever heard of something like this? Or is it possible the champion gone the el cheapo route and started buying the absolute lowest cost product they can find and putting their name on it?
