spark plug poll

[Elmosac]

I am running E3 plugs right now and love them.

I had to order them from E3 as no one in town seems to stock them

They have 3 electrodes and direct the spart straight out of the bottom of the plug which means you don't have to index the plugs to maximize performance.

i run plain hd plugs, they run fine in my bike, my dads 85 fxstc bike, he has a hyper charger on it and it will foul a hd plug in a second, he runs and believes in his autolites,. they never foul

I am going to have to change my vote. I put 2000 miles on the autolite's and on my way home the other day they started acting up. Got home and put my old H/D plugs back in and the bike is running great again. I guess it is Harley plugs for me.

Hard to beat the HD plugs IMO.

I have a carbed bike and I use Champions spark plugs.

Yesterday I had installed HD spark plugs.

I use the Autolite plugs and have had good success with them. I also index the plugs when I install.

10,000 miles on my autolites might change them for peace of mind

Never had a problem with NGK

I run Champion plugs in both of my bikes. I do change them at each fluids change (interval of around 3k miles): engine oil, transmission gear lube, primary fluid, oil filter, plugs.
