Just wondering what the best spark plugs people have been using on 2007 Softail NT.


My bike has PCIII
Big Sucker 1
VH Shortshots Staggered.

Thanks!!!

 

Not being smart or anything, but why would someone change spark plugs so soon?

 

I change my plugs at every oil change and I change my oil every 1,500 miles. 4 quarts of Amsoil & 2 plugs are cheap enough compared to all of the other expensive mods I have. I run the **** out of my Train, thus better safe than sorry.

 

From my experience and feedback from guys here, not much benefit to running high performance plugs with a stock motor. I use the stockies.

 

Holy hell your wasting a lot of money you don't need too. 1500 mile oil changes and plugs every oil change :O I don't care if you run the **** out of your train, that's just uncalled for. Get an oil analysis done and Ill bet you a case of what ever you drink that your oil is good for at least another 5K miles. But hey what ever makes you happy (and lighter in the pocket.)

 

Yeah, I know its good for 5k (I work for a Petroleum Company); but habits are hard to break. I change the oil in my cars at 1,500 too; not the plug though.

 

I have about 4,000 miles on it and just wondering what (for the future) people are using. I have heard from people changing them every 5,000 miles just cause its so cheap and just want the best for their bike and others saying a lot longer.

 

just did my 5K maint through Harley (yea waste of money, never again) and they automatically change spark plugs at 5K and 10K at the dealer I got my bike through.

 

I change mine at the beginning of each riding season, $10 is not a big deal, NKG plug is always my favorite.

 

I'd just run Champions and change them between 5,000 and 10,000 miles. High performance plugs don't make that much difference.
