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.

 

Thank you nvsteve.

 

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.

 

doc what number NGK irridiums would i use in my built twin cam 2005 deluxe built 95 every thing but a strocker

 

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

 

+2 on the NGK Irridium plugs. Thats what I will always run in my bike
