[bripaintball]

i own an 03 polaris classic 700, and an 04 classic 800...i was told to use the champion copper top plugs for the 800 but not for the 700...should i be using the good old NKG BR9ES???? the copper tops keep getting the tabs smooshed in by the engine,,,i cant imagine that is good for the engine...

any help would be greatly appreciated..

i always stick with the mfg specs. unless you have some major mods that require a different plug. here's what you should be running.
BOTH SLEDS!: Champion RN57YCC, P/N 3070190
use these plugs and you should have no problems. they are a dual heat range to prevent fouling and enhance performance. good luck! -Polaris Doc

My spec sheet that came with my sled stated Champion sparkplugs, however through personal experience I find all Champion plugs to be garbage. Throw them out. In fact, my sled came with NGK plugs, and when I asked Polaris for spare plugs, they gave me NGK plugs. There's a very good reason for that: they work. The current plugs in my snowmobile right now are the original plugs, they have 641 miles on them and counting. I did have a different set of plugs in, however I let the machine run above 190*F once and it burnt one of the plugs, so I put the originals back in.

Also, if the champion plugs are getting damaged simply by starting the machine, that is the first sign that you should not be using them.

Junk? Tabs smooshed in by the engine?

I've never been much of a Champion guy when it came to sleds either. But they told me there is no direct cross reference between the NGK and Champion for the recommended plug type. I hesitated/complained a lot at first but just got used to the idea of having to stock a new/different plug number for this hot rod 800 I had just purchased. That was several years ago. Now, with nearly 15,000 miles between the 2 of them. I have no reason to complain. I doubt I've fouled more than 2 or 3 plugs the entire time. Having trouble understanding why anyone would say they're junk. No worse than NGK in my book.......

Not quite sure what you mean. Are you talking about the terminal at the plug cap and if so elaborate on why they are getting smooshed.

the bPr plugs are an extended tip plug, effectively does the same thing as the rn57ycc
