Plugs.
You might get a bit more (undetectible) peformance by indexing them. Other than that, not worth it unless you want your plugs to last 100,000 miles, in which case get iridium ones.
Since it's so easy to pull a plug on a Sporty, I've never bothered.
Now PULSE plugs, that's something else altogether...
Do you people know anything about physics? Or is it just, (I start my bike and ride it).? So tell me what is the difference is between 87 or 93 octane? So what oil is better? It all comes from the same cow you dumb ***! It's the things they change or add to make it work better. As with a spark plug. The metals they use didn't exsist 20 years ago. Am I making any sense? Don't mock me for asking a question again! HOLLYWOOD
Granted. A plug is a plug, but there are better one's out there. Just want something better than HD plugs HOLLYWOOD
And here we have someone that has never been around a scope long enough to see there are some major differences in plugs from one manufacturer to the next even though the plug is supposed to be for the same application. If a plug is a plug then why would there be better ones out there? Don't believe it? OK, take either plug out and put in a plug from wherever. Plug the bike into a scope and watch the KVA output difference between the stock plug and the aftermarket plug. Some times you will find the stock plug doesn't have the same KVA output the aftermarket plug does. Some plugs foul out easier than others too. I run the Screamin Eagle Triple Platinum and I am on the same set of plugs I was 3 years ago.
crapshoorter thank you! The way the flame proprigates from the spark plug most people don.t understand that. The better the burn, the more horse power you make! That's all I want. HOLLYWOOD

The efficiency of the burn can help in fuel mileage as well.
