According to J&P Cycles these plugs will not fit the Bagger Harley FXR 82. Not only do they fit, they are the best plugs I have used in 30 years of ownership on this machine. It started with 80 cubic inches. It now has 93 inches of high compression stroke and loves those plugs a lot.

I noticed the difference straight away, the bike starts much quicker and easier, the bike is a little springier and the exhaust sounds a little louder and crisper which I like. The bike also feels a little smoother. 1999 Harley FXSTC. I'm surprised that spark plugs make such a noticeable difference. Definitely recommend them.

This spark plug is pretty good. I have an old Harley Shoveled and it can be prone to cork fouling. I just bought these plugs to replace the same ones I've been using for about 4 years.
