Comments about E3 Premium Special Electrode Automotive Spark Plug:
The acid test would be if I'd done a dyno pull with a new set of 'standard' plugs then another pull with these. I did not do that.
I can tell you they work as spark plugs - how much of the hype you believe is up to you.

Comments about E3 Premium Special Electrode Automotive Spark Plug:
I'm just an average everyday driver. I fell for their claim of better fuel efficiency. If you are planning to buy this plug to improve your mileage, don't bother. Buy the regular plugs for your vehicle at a MUCH cheaper price. My mpg is the same as before in my 2008 Hyundai Elantra. Happy New Year!!!

Comments about E3 Premium Special Electrode Automotive Spark Plug:
I installed these plugs in my '99 4.0 SOHC, slightly Race modified Ford Explorer. These spark plugs initially impressed me with what felt like a little more power but after 2 days, started misfiring and lite up my "check engine" light. OBD test came up with misfire. Never had this issue with any other plugs. Removed and went back to Autolites. Need to look into how to get refund.

I can feel a difference but have not had time to test out milage change. Hoping for at least 6-7%.
