Kinda confused with the plug, I picked up my new 2015 570, owners manual says the plug is a Champion RG6YC which crosses to a NGK CPR8E but the plug in it is a NGK MR7F. There is no such plug on NGK site, Pats store doesn't show one and dealer has no idea, there book says RG6YC. Any one else had this.

 

Can't find one either,but I'd be leery about it and change to the direct crossover NGK plug which shows the CPR8E.

 

The NGK MR7F is a dealer only plug. Your local Polaris dealer will stock it.

 

Found them at several places,but just a standard nickle plug,copper core.NGK 3066 CMR7H Nickel Spark Plug
NGK 3066 CMR7H Spark Plug Plus doesn't show to be a crossover to the Champion RG6YC ? The CPR8E does.. Anyway,I'd rather use a NGK and save the Champions to lawn mowers and weed eaters where they seem to work the best... Sorry one letter off on the plug.. Here's one guys question on the same thing. If dealers are trying to corner the market on a "special" NGK plug,think I switch to the CPR8E anyway when it's time to replace them.

"OK, I'm sitting at work trying to get a list together of spare parts that I should carry along with us when we ride. The first thing that came to mind was an extra spark plug for each machine. So, I started to look through the manuals to see what plug was specified. That's were the confusion begins.

The manual for the Sportsman 570 calls for a Champion RG6YC plug. The manual for the Ace 570 calls for an NGK MR7F. Isn't it the same engine? Shouldn't they both be running the same plug?

Also, I have been reading where everyone seems to prefer the NGK over Champion, but I cannot find anything about the MR7F plug. :nixweiss:

Again, I'm at work and cannot look to see what is actually in each one. Should I just switch to the CPR8E plugs and call it good? "

 

The dealer was out of the plugs and have some coming in but all the order shows is the Polaris part number so they won't know till they come in if there Champion RG6YCs or NGK MR7Fs. My plug (MR7F) is really white so that tells me it's to hot of a plug. Have read the Ace plug is different than the Sprtsman.Why would the Ace 570 be running a different plug than the Sportsman 570

 

Jetting, different carb or exhaust system set up,air filter box,or filter difference could be the reason on different plugs. On efi systems plugs do run leaner for the most part,but shouldn't be white..

 

I can understand the diff with air box, exhaust and jetting between the Ace and Sportsman but they are all efi. All Sportsman are the same so why do some have one type of plug and others have a different one. Something just doesn't seem right. When I told my dealer what plug I have they couldn't even come up with it.

 

Plenty of times we didn't know at the shop what Polaris was doing when they made changes. Frustrating when they did things like this,then later on we might get a tech bulletin..

 

I've read other threads about Some of the earlier 570s having the MR7F plug. It's pretty bad when the parts department knows nothing or Never even heard of that plug when it's been used in earlier models. Guess I will try and send Polaris an email to see what I can find out.
