Thanks guys, that's all I wanted to know, The first few answers I got were not very clear, Just wanted to know if a better plug was out there! So what I get from you boys, it's just media hype. They all run about the same. I will go with the platinum plugs. Part of my problem was BOTH plugs were gapped wrong from the factory! Checked the plugs when I did the first oil change. One was at .028 the other was .035. Go figure? It's gotta be .038 to .042. I'm gonna write a real nasty letter to someone at Harley today! Take that to the bank! Thanks again for all the imput............HOLLYWOOD

No, take 8 plugs of different manufacturers all for the specific application and put them in. then look at the scope, which is what we did. That's how we found out the R45TS was superior in that test. Iffy has nothing to do with it, the plug either does or doesn't put out more.

So what is the verdict? Should we just run the standard plug, or some aftermarket bullsh#t? I know I opened a can of worm's on this subject, many thanks to all of you!

Manufacturers pick plugs that work best for the engine design they built.I work on cars for a living.If it came with NGK it gets NGK back in it.Gm cars get A/C Delco.Ford gets Motorcraft.I used to work at a shop that stocked Bosch plugs,platinum by the way and they were the biggest headache I ever had concerning tune up type work.I had an older S-10 that came back with a multiple misfire.3 of the plugs had bridged electrodes from the platinum coming out.It was the correct part number I double checked.When my bike needs plugs it will get the factory installed replacement.

Hey guys, I've been searching threads on here for several hours and looks like you all could help. My bikes been running like crap, so here's the scoop on the scoot:
2008 Fatboy Stage 1 download w/ V&H bigshots and K&N filter.
8500 miles currently
The rear plug looks VERY light grey and the front looks OK in color but deposits on the base of the ground electrode. Exhaust is about the same in color. No pop on decel. Sluggish on accel, smooths out about mid throttle but seems to run hot. I run ethanol free 93 consistently.
So should I:
Be concerned i might have debri somewhere in the line since I painted the bike over the winter?
Consider a tune (if that is your thoughts, I will not bother you with it on this forum)?
Buy new plugs and not worry about it if it's running fine?
Go to the dealer and use my best tool - the checkbook.
Thanks.

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

plugs
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.
