I don't know if it really make difference or not, but it is recommended to use non-resistor type plugs .
I wasn't aware of this and used Bosch platinum resistor plugs for a few years, got 4 plugs for $7, close out special, never had any operational issues when using them .
I won't ever use them again, the center electrode was recessed into the ceramic, best I could tell, the gap was over 2 times what it was supposed to be !!!
This was at 8,000 miles, 11,000 km .
I've gone to NGK plugs ever since Bosch plugs stopped being available in non resistor type .
If you put non-resistor ignition leads on the bike, then you can use the more common resistor plugs .
