I some cool new spark plugs for both 2-stroke , 4-stroke , small engine and big engine.

E3 is an entirely new kind of spark plug producing 8%-12% more power while increasing fuel efficiency up to 13% and other one ENGRGY increases both 2 and 4-cycle power up to 8%-12% over other brands better combution reduces carbon build-up and extends engine life.
EFFICIENCYuse less gas-as much as 13% less versus other spark plugs. Work longer with fewer fill-ups.ECOLGY reduces toix emission up to 58% in long-term use, versus the leading spark plug. Do you think some cool? I have one spark plug number is BR7ES for my on xplorer 400 4x4.

I put one in a 10 hp gocart. Ran for about 3 days and the threaded top viberated off and was lost.
I called E3 and sent e-mails....they never did respond.

I would make sure the top electrode can't come off, if you get one.

 

stick with NGK. thats what polaris wants you to use. if you want you can upgrade to the NGK IRIDIUM.

NGK IRIDiUM are cool

 

No the plug is ok, I replaced the top and crimped the top edge so it would not come off.

Not sure why some plugs are made like that?

 

the reason the cap threads on and off is because of the different spark plug connecters. some push onto the threaded part and others push over the cap thats threaded on. when you buy a plug that has a threaded cap always take some pliers and make sure it is tight before using it.

 

On my snowmobile, I had a problem with a black debris build up on the threaded caps (possibly causing added resistence) that were silver in color. I replaced those caps with brass caps from some automotive plugs. Problem solved.

 

Spark plugs E3. Do you have a trouble with your spark plugs E3? You will let me know ok. I will try one a new spark plug NGK IRIDIUM what number is? For my xplorer 400 2-stroke.

When I checked the NGK site. It gave me BR8EIX.........But it also said that it replaced the Original plug that was BR8ES. In your post you said that yours was a BR7ES. Someone on here with the same machine might verify for you that the OEM was a 7 and not an 8. Anyway there great plugs....runs you about $6.95. I got mine from Oriellys auto.
