    The R is for resistor plug, the resistor prevents the spark signal from intefering with the ignition system.
    If your application calls for a resisitor plug make sure to run it, the consequences could leave you pissed off.

    correct.

    the "P" in the plug number stands for projected tip. this too is needed for polaris. the b8es has the std tip.

    The 92 Polaris called for a BR8ES without the projected tip but honestly I have run both and can't tell the difference? but the projected might not foul as quickly? if you have fouling issues? Z

    honestly, there is no available 8pr8es or br8es here...so im using b8es....is this ok to use???

    Well you really wan't 7's and kinda need the R= resistor to keep the CDI happy 8's are a little hot! can you atleast find BR7ES Common generator plugs for Boats ideally BPR7ES Z

    Z, I've heard the 7's are hotter than 8s. Anyway, the 7s are only recommended on '97 SL700 DLX/SLT700 '96 Hurricane '96 SL/SLT700 and '92-95 SL650/STD SL/SLT750. All others use BPR8ES according to my book. Andy, It is critical that you use the proper sparkplug as electrical parts may get damaged from the wrong ones. I know it's not easy getting parts where you live, but you will just have to order them from the U.S. Sorry to say, but you should've ordered some from Zig with your other parts.

    Wow I had a dyslexic moment! You are so right! 8's are the plug heat range of choice!! Thanks!
