Re: spark plug poll

I doubt you'll see any "change" until you get a few miles on them. THEN if you change back to a stock HD plug, there's where you see the difference. Been there done that!

Re: spark plug poll

Re: spark plug poll

I usually go for plugs at 10K or once a season.

Re: spark plug poll

HD. There are plenty of things HD sells I won't use. (ie: Syn 3) but plugs are not one of them. I will stick with HD.

Re: spark plug poll

I believe in using what the bike comes with from the factory as they always seem to work well. I do the same with all my vehicles. If the factory uses them, they must be ok. Just my Opinion .

Re: spark plug poll

I tried Autolite's they work on my 06 heritage, but the HD stock 6r12 (champion) work the best with the 06 resistor sensor that measures plug resistance, then the bike computor changes to the resistance.
