If you bought from Amazon themselves not a third party selling on Amazon and Rock Auto I don't believe they were fakes. These companies have too much to loose engaging in such shenanigans.
I read an article a while ago that this was happening because Amazon was grouping products together for better effeciency at their warehouses. So, for example, Amazon might have 1000 plugs and Company A, Company B, and Company C each send 100 plugs to the warehouse that they want to sell. They get combined together (now 1300 plugs there). Now if you buy "sold and shipped by Amazon" you might actually get a plug from Company C which happened to be fake. Likewise, you may choose "sold by Company C shipped by Amazon" and get real plugs.
Not sure how prevalent this is, but the logistics made sense, so I could see it happening.
