Just posting a question to see if you guys are still running NGK plugs in your Sportsman's?
My dealer put in Champions in both my 2006 Sp 450's when he did the first service and there still in there!
I remember asking why the switch ,He told me something about the idle and lower RPM range the champion are a plug that he recommends putting in ....Now with over 2200 miles I can't really argue with him!

I"m sure NGK would have been fine,I run them in my sleds from day one.
Also before I end here,How many miles do you guys go between plug changes?
I think I am do for a change right about now.
.....Caper.........

 

I've used the NGK plugs for about 2500 miles and have had good luck with them.

 

I'm running NGK's also..

me too. 2700 miles on 2 plugs(just because)..

 

Thanks........I might try to put the NGK's back in when I do the change ........Caper.........

 

im running NGK, had some problems a while ago but it was more of an air/fuel mixture issue than the sparkplug... now everything runs great and have not had any problems

 

Got NGK's in all of my quads. How often I change it depends on how easy it is to get to. Granted the Trail Blazer is a 2 stroke and I check it more, it's also easy to get to. The KFX on the other hand is almost like doing brain surgery to get to it. Generally, I have two plugs for each quad. I may pull the first one after a year and put a new one in, but I'll clean up the other and keep it just in case the new plug fouls for some reason. Then the next year swap em out and clean the one I removed as the spare.

Basically just rotating spark plugs.

 

I don't even carry spare plugs with me on the trail....LOL....LOL..

not like snowmobiling...........I carry 2-4 plugs at all times ..But never need them ,unlike the sleds from the 70's...................Caper.............

 

I bought a box of 4 for $8 NGK at the AutoZone. That is what I run, no issues!

I run the NGK Iridium plug in my 02 500HO. Made starting easier and cleaned up the idle. Been in there for 2 years now with no problems at all. The poos are set fat at the factory and this plug and a K&N filter has the plug a nice tan color now. Before the old champion was fat black.
