Sorry, if you check out the site you can see more of a gap on one side.. I'm not here to say that this will bring more power or is better then anyother plug, but it seems like it's not much and it's more taking up ur time if you have to go back to NGK's..I'm sure this plug will work just fine.. Who ever installs it 1st let us know what you think of the E3 spark plug pls.

Oh I see... Thought those were three unattached electrodes... can see where indexing would have some fine tuning advantages. I am Very curious az to some reports on this plug..per Brett.

I tried them in my 1500 Vmax Tourmaster. Was not impressed. Worked fine. Just not better.

I have used these is my Commercial lawn equipment 2 stroke for a while , But i know this on outboard motors that call for iridium
plugs you must stick with that protocol cant see that the E 3 plugs are iridium and I think thats important , They were not any more
impressive in my 2 stroke stuff but that equipment has a lot of factors including mixing oil and gas and Carb. instead of fuel inj.

Are the E3's iridium? If not, who makes the best high performance iridium?

Hi Correct me if I am wrong but on my Max the plugs are NGK Iridium CR9EIA-9
Does it differs in europe and US??

Yes, those are the correct Plugs. I get them for around 9 Euros each. I'm not sure, but i don't think US and Europe shouldn't use different Plugs. That might be something else in really hot Climate, like Australia in Summer or the Gulf Region.

I've always heard that Denso Iridium are the best.

That might be the Case, but excuse me, i ain't gonna pay more than twice as much for Denso Plugs in Retail, whereas i get the NGK's from a Wholeseller at said "cheap" Rate. Standard NGK Plugs are at 2.60 Euro here. I won't pay 17.00 Euros each for Denso Plugs as long as the NGK do the Job only a Tad less good than the Denso's.
