You can check or call your local store ,one may have them and others not. Now all bs aside . Most high performance shops run regular autolites. I have run 1 set for 10,000 miles in a 95" 115hp motor . Never had a problem. I would check them and add some anti=seize at oil change time and put them back in. I could get 42 mpg no that carburated heavy bagger with that motor . If you have a good ignition system don't worry . I don't go to harley for much of anything ,in 25 years only in the shop 4 times and they screwed that up. Do must of my own stuff and damd sure do my tuning. If you have a 80,000 volt system and a 14.7 air/fuel or higher like some of cars then sometimes those fance plugs help but what we have on these bikes is still early 80's tech.

I like www.sparkplugs.com.

I order a bunch of plugs, for all of my vehicles, each year, all at once to save on shipping.

I love fine-wire iridium plugs, run them in all my vehicles. Hardluk is right, your vehicle may not need them, and you may get no advantage (and be out a few bucks). Some of my more tempermental vehicles (prone to fouling, etc.) DO need them, and they are MUCH better than normal plugs there. So I run them in each vehicle that will take them (correction, not my cars, bikes only).

Loved the NGK Plugs they way they work in My Sportster and worked in my Heritage Giving them a shot in the New Electra and will be the first to let you know if any problems as said may not gain anything but sure don't think will lose anything either except perhaps a couple bucks extra spent...

Just ordered two from Napa. They were able to find them in their books. Ten bucks each but need new plugs. Just rolled 10k on my 2003 Road King.

I'm running NGK DCPR8EIX in my 2010 Ultra Limited. The DCPR8EIX is one heat range cooler than the DCPR7EIX.
