850 Spark Plug..think I found something other than Champion..

[08700efi]

idk about their wheelers but Polaris recommends champion plugs for their sleds because the porsolen sp? is less porous and they do not foul out near as often as ngk

Any thoughts?

found them on sparkplug.com for $12.06

Same plug..6043 is just the part number. I've had them in mine for a few hundred miles..they show no real signs of wear(gotta love iridium) and it purrs like a kitten.

Whatever is in the manual....034 or .035 I think it was? Can't recall off the top if my head but whatever Polaris specs in the manual(not on the sticker on the frame)

BTW I have experimented with wider gaps with both the stock plugs and the NGKs...interestingly the top end is noticably improved around .040 but idle quality suffers some...the only thing I can figure is that it is the way they have the timing curve set up on the 850 causing it to missfire at idle with the wider gap but not under heavy load.

Sorry..just saw this..

The Dynojet PowerCommander V is said to have that ability..should be out any time..I heard a couple weeks about 2 months ago..it does exsist according to Don at Diamond G Racing,he was involved in the testing..just a matter of when they actually make it to market.

Go to this site, and put just that NGK plug number in the search. It returned plug "ILZKAR7A10" in NGK Iridium.

Club Plug

EDIT: Now, the question is... do they really have them, LOL and, is it the same plug?

I just ordered those NGK Iridium plugs for my Nissan Maxima and from what I'm hearing it makes a world of difference in fuel economy and performance!
