I read mixed reviews on these plugs, I said the heck with it and tried em anyhow, glad I did! No more hard starts and a noticeable improvement in performance. Highly recommend them

I kept reading bout the E3 Diamond Fire Spark plug and how good it was. I'm basically Old School so making changes from the Norm is not something I do. But I decided to give these a try on my Motorcycle. 1st. the Manufacturers of this plug makes a large assortment of sizes and configurations for different applications so make sure you Get the Right Plug for your Ride. 2...The Gap on this is preset...you cannot set or change the gap. Ok This said, I put these on my Bike and Started it up....It was cold outside [Winter] and the bike was cold. She started right up and Instantly I could tell the Difference in sound and smoothness. Fuel Enrichment off and she settled into the smoothest Idle I ever hear with her. Upon a 5 mile test ride, the performance was awesome. Throttle Response is crisp and immediate..no lag what so ever. Bike actually had more punch than normally....I felt like I had gained about 5 horsepower more. I read that the Fuel Mileage should increase as well...so time will tell the story of that aspect. Overall the plug is a Little more than normal plugs will cost but well worth the price. You have to buy 2 plugs separately. or how ever many your ride uses....they sell individually.

These work, but you can't adjust the gap with this design. So that's weird. I'll get different ones next time.
