Are there any other spark plug options other than the HD-6R12? I'm running a stock TC and looking for a cheap performance boost.

 

yea, they have high performance ones available from Harley...

Double Plat. are 7.95

Gold are $4.95

their are some screaming eagle ones but depends on model and stuff...Everyone I have talked to said the stockers are fine, but I might try the Double Plat ones next.

 

i saw this on youtube, and i found this

thanks TK...good chart.

 

from what i have found a stage 1 only needs the stock plugs and i gain nothing from changing them. also i think the plug wires are so short they would not matter. a high performance coil would help. i would like Accel if they made one
found one http://www.accel-motorcycle.com/Prod...&minselection=

 

everyone has told me that stock is just fine. no reason to switch to any other. they are cheap enough also..
