I use NGK V-power plugs now. What alternative choices are out there? I know I need 14mm gasketed 3/4 reach. Do I have to use 5/8 peanut or can I use 13/16 or 3/4? I would like to try one range hotter plug than the #7 offered by NGK, they load up in traffic and could be a little lighter colered after a long none stop run. any help would be appriciated. by the way the #7 NGK ran fine before I changed out to a longer duration cam.
