E3 plugs made noticeable improvement in my gas milage and acceleration . My son recommended them to me , LOL, i was going through 2 & 3 sets of plugs a season with champion ... so no more of them for me . These E3 plugs last and keep their improved performance. I do highly recommend them to all who Ride .

This is not my first go-around with E3 Spark plugs. At first, I was sceptical because of the limited variants. With a plug such as Champion, there may be 4 or 5 different heat ranges. With E3, the one plug covers the entire spectrum of usage. I am a bit OCD when it comes to oil changes and spark plugs. I change my oil every 3,000 miles, and change my plugs every other oil change. I do not own an automobile, and I am retired, so it is not unusual for me to ride 3,000 miles in a month. I check my MPG every fill-up. Most of my riding is on country roads. I avoid interstates. After installing the E3s, I noticed that my gas mileage had gone from 36.4 mpg to 39.7 mpg. The gas mileage has stayed at 39+ since changing from the Champions I had been using. I did not gap the E3s as the gap from the factory was "close enough" on both plugs. Far superior to Harley Davidson OEM and better than Champions. Fast starts. I don't own a Dynomometer, so i can't attest to horsepower, but I ride like a very seasoned Motor Officer. No drag racing or high speed runs. I will purchase these again when i need to stock up.Read full review

My atv runs great with the e3.36 e3 plug. Of course it's a Honda so it would probably run great anyway but I like the e3 and I say try it what have you got to lose. You might even gain some hp with it.

After reading all the hype about E3 plugs, I decided to try a set in my 1997 Honda Valkyrie. I can't say that I'm really impressed. No difference in performance but I did lose a mile or two per gallon. Before the riding seson is over I will most likely put the old plugs back in the bike.

I had already been using these plugs and was in need of new ones. They are great no problems at all the other ones had been in the bike for about 8 years.
