Let me try that again. The book says to use RC74C Spark plugs. The guy at the dealership gave me RN57YCC plugs.. Anyone know the difference?

Thanks,

Hank

 

I believe the oe plug was a champion "rn7yc", but most have switched to ngk plugs. The correct ngk plug is "BKR7E". Your
local auto parts dealer can order them for you if your polaris dealer doesn't have them. I haven't heard of either plug # you mentioned
before??? Sounds like he gave you the wrong plugs. Go with the ngk's, you'll be glad you did. Dan
