I wanted to let you know that ngk does make a plug for your 850 infact they make 2 different ones, you can buy the ngk resistor plug for about 6.99 from rockymountainatv.com the part number is LZKAR7A the other is an ngk iridium plug you can actually get from your local autozone or napa, or any of them, but they are not cheap, somewhere between 15.00 and 23.00 each. i hope thai helps you out. i went through hell trying to find a plug outher than the champion plug.

Just from what I've found,but never replaced the Champions before I retired. You might want to check em out a little further as to where they're a direct replacement. NGK 2010 Polaris 850 Sportsman X2 850 Sportsman Spark Plugs | J&P Cycles

Others may be able to help you on this better than me. I never found the correct NGK replacement plug while I was still working,they changed the Champion plugs TWICE on us!(or I would have chunked the Champions quick)but times have changed and there should be one available by now.

Just don't hit the throttle before it has time to warm up though! This I don't think has changed! It's because when you first crank any efi (especially the 850) the engine goes into a "waste spark,waste fuel" mode until it receives a signal to the ecu from the the sensors. This we found out quick when we fouled plugs out on the first ones !
