Default right plugs?
I have a 2003 softail standard 88" just wondering what are the correct plugs to use I have plugs in I installed last year on the advice of someone maybe I should not have listened to, the only upgrades is a screamin eagle heavy breather and screaming eagle double barrel exhaust. I believe I am going to order a fuel moto PC from jamie will that make a difference in plugs?

Stock HD plugs are fine for your bike including your planned mods.
I like Autolite 4164 and NGK DCPR7E.

Be aware that autolites are a different socket size than the champion 6r12 that Harley sells. They are an 11/16" instead of 5/8" I have run both but run the NGK irridiums now.

I've got the iridiums in mine now also. Don't notice any difference but they'll probably last longer.

Not Doc, but:
DCPR7EIX would equal the stock plug.
DCPR8EIX recommended for 10.0 or higher compression.
