I've ran the oem hd plugs, champions, autolite and ngk. Until I removed them I had forgotten what I had installed, thats how memorable a brand change on spark plugs are.

Truth. Any claimed gains are 99% just because you're getting putting in a new plug, and the old one coming out is worn and degraded in performance.

Has anyone tried glow plugs? I would think you could then put diesel in the bike and double your mileage. Maybe we can get hawaiian guy to try it.

Just the standard OEM HD plugs.............No issues and they are more than adequate.

HD plugs here to.
I change my plugs every 10,000 miles on our HD bikes except the super glide. Pro Street 113. I have to change those at 7,000 to 8,000 miles. It gets to stubborn to crank well.
New plugs and it's good to go.
