The factory recommended plug is NGK BR8ES.  Some guys on hear run NGK B8ES, which is a non-resistor plug, but in all honesty I'm not certain why...  :shrugani: Maybe somebody out there knows the benefit or reason.

Because they are the exact same plug performance wise, only they are cheaper...and I don't have a radio on my shee so I don't care...

From the factory, it is a B8ES. Reason why, is that the Banshee has what is called "loaded" caps. The loaded cap refers to the spark plug cap being loaded with a resistor. This is the same thing that is in a BR8ES plug. If you switched your plug caps, (they are known to go bad) and you didn't replace them with loaded caps, you NEED to run an "R" style plug. Otherwise, you will damage the CDI from the back and forth run of electrical currents in the system. Running loaded caps and an "R" style plug isn't a problem either. Just a little extra insurance that nothing will happen. For the minimal extra cost, I don't htink it is worth not having an R plug. I run one set of plugs per season. I don't have any problem fouling them. I don't remember the last time I fouled a plug. But, that is the mystery behind the resistor plug, and why it is/isn't needed on a banshee. If you have stock caps, don't worry. If you don't, you better worry. :cheers:

the new irridium plugs (BR8IEX) work kick ass and I'm on year 2 with the same set, absolutley awsome throttle response!

awhile back I had to replace my plug wires, didn't really know they had resistor in the stock wires at the time, I replaced them with some 8mm plug wires... I was in the back yard the other day, parked near the house revving the motor, well it was actually causing interfernce with the TV inside the house.... :bolt:
