I'm simply stating personal experience while working on cars (I was a dealer tech for close to 20 years) One vehicle I remember specifically. The dealer I was working at, sold a used F150, and within a few days of sale, it was back with multi-cylinder misfire/CEL on. Swapped out the near new looking Autolites for a set of Champs. Problem was fixed. Funny thing is, I also use Bosch Platinum plugs in stock daily drivers. Many ppl say those are crap too, I never had issues with them either. lol
I don't believe the marketing hype about most products out there. I buy, I try, if it works, I keep using it. So use what works for you. Again, I'm only sharing my personal experiences.
