"E3" Brand Spark Plugs for Valk - Anyone Have any Experience with these?

[Big Ed]

They are supposed to improve performance due to the way the electrode isn't blocked like regular plugs. Thought?....

i have 'em, don't think they made any difference.  fuel milage stayed the same, so did preformance.  as Robert said, snake oil, unles it makes you feel good......  i'd stick with NGK, that's what i'll go back to when the day comes....

My experience with them is pretty much the same as Alph's. The bike runs fine with them but it ran fine before.
No mileage or power gains that I could notice.

just an expensive version of an old racer trick of cutting back the side electrode. for street applications cut the SE back half way, so only half of the center electrode is exposed. then gap the plug on the low range or slightly less.
to some its a noticable difference. I run mine this way and in all of my vehicles.
easy no cost mod to try.
