Review on 🔥 NGK 5422 Spark Plug BR8ES - 4 Pack: Superior Performance & Longevity! by William Stewart

Never had any luck with NGK spark plugs. My old British Norton bike will always withstand these Japanese uses and trample them to death in short order - usually within a few months. My new owner's manual for the Indian-made Royal Enfield specifically recommends this type of NGK BR8ES, but I may have gotten a bad one. He started behaving within a week - maybe just 100 or so miles. A check outside of the engine revealed that there are sparks almost everywhere except the center electrode. Now I have a slightly "hotter" champion N4C and everything is fine. I contacted the SfloridaD seller about the problem but never received a response, refund or replacement. Not that I'm likely to want to use the new one for anything, but maybe as a fishing load for now. Suffice it to say I will never use them or NGK again if I can.
