Answer 1

i've always just bought the plain standard plugs from hd, not the screamin eagle or platinum or whatever... don't believe in them... hd std plugs are comparable to any jobber for pricing

Answer 2

HD plugs or Champion plugs (they make the HD plugs) should be fine.

Answer 3

Denso

Answer 4

I use champion plugs. They have always worked well for me in the past and I figured why change what works.

Answer 5

I don't know that you can tune a Harley engine enough that it will need fancy plugs. A set of Bosch Platinums from Autozone should work well enough that you won't notice a difference other than that you'll be able to buy a case of good beer with the leftover cash.

Answer 6

Harley-Davidson 6r12s. Just the standard plug. They're cheap too.

Answer 7

I liked NGK in my other bikes.

Bosch platinum worked great in the cage.

I currently run stock HD plugs in my TC88. They work ok. I never liked Champions for anything other than a Briggs and Stratton. Next set will be NGK.

Answer 8

I've used every kind of spark plug known to man kind and a regular HD plug is as good or better than all of them. Auto Lite platnums are also very good.

Answer 9

Personally I don't care for Champion plugs at all. I use either Auto-lite or motor-craft, unless I have a few extra bucks and the I go with the Bosch Platinum. The last set I had lasted over thirty thousand miles. You really can't beat that!!!!
