I Used to only use Bosch Platinums, but when I started getting into Japanese cars, I found that ngk worked the best for me. Just whatwver you do, don't use splitfires... one day at the dyno I seen a guy jump 10hp (sportster 883) from swaping from splitfire to regular old Champion plugs

i got some platnum plugs for my 30K service. i think i can go longer than 30K now. ill pick up the iridum plugs next service. They were special order from the parts store and i wasnt waiting for a day or two for spark plugs.

the xp is a irridium plug....its a .6 irridium finewire core double platinum sidewire design and with this design they have increased the kernal flame making it a HOT plug making it fully burn everything here you can check em out
