I've been running NGK plugs in both my sleds for years and never had an issue.

 

NGK's are a great plug- what do you mean "eats through them"? If you're fouling plugs then you either have the wrong plug or you are running too rich and need to clean/adjust your carbs.

 

i think ill just stick to champion theyre way better

 

Not to be a prick, but what's the point to this thread, and so many like this lately? Are you interchanging the correct NGK plug for the application? I know the newer Polaris Liberty Engines use a Champion plug that doesn't have a 100% exact cross for NGK. Are the gaps the same on the plugs? I have over a 1000 miles on the set of NGK plugs in my sled. If you need help or have questions just ask, someone on this site will be able to give you a educated answer to your question.

 

Ive never had a problem with NGK's either. Never fouled a plug with 1075 miles. I just change them once a year for good measure and keep the old ones for back ups for me and who ever I ride with. Ive seen champions foul alot more than NGK's.

I went to royal distributing the other day, (who only sell ngk) and the guy behind the parts desk told me NOT to buy plugs from him. He said since I have a polaris, to go buy champion plugs from somewhere else. I figured he would probably know better than I, so I went to canadian tire and got some champs.

 

I just bought some NGK plugs last night for my fusion. I was not in need of new plugs, just figured its nice to have back ups.

 

I have been running NGK for 25 yrs, in polaris old and newer , have never had a problem!
I agree with TripleB you must have something just not quite right (carbs/gap/type),unless your using old plugs that rolled around in the back cubby for few years.

 

Plugs are plugs,champion,ngk,they all work as long as you have the proper plug/heat range for your application.Just my .02.

That's because the liberty motors are built around Champion plugs. Like stated above the is no exact cross-reference for NGK and Champion.

 

It's been my experience that in the fugi motors the NGKs worked better than the champs- I've heard the newer libertys run good on the champs. Whether you like NGK or not the fact that the BR9ES is probably the #1 selling plug for sleds speaks for itself- places can't keep em in stock.

 

yeah wow i dont think its the plugs! its the snowmobile i put plenty of miles on my machines from snowmobiles to dirtbikes and i run ngk's in my cars and trucks. never had a problem. if you go through so many plugs why dont you get all your used ones put back together on a baking pan and bake them and re-gap and reuse! works great. i just did like 12 of them that i found over the years and i use them for backups.

 

put a torch on em and they shoudl be fine as long as you get them cherry red. you can boil them to

 

ya i used a torch to either way works

 

I run NGK plugs and caps in everything and never had a problem.

 

I never had a problem with plugs. I use NGK for 2-3 seasons and only problem I have when there is a problem with my carbs settings. I also sandblast my old plugs cleans them up like new and use them over and for back up. I also used Champion and AC when I can find them. Plugs usally last awhile and there basically made all the same. I think the heat ranges differ but the all made to do the same thing. Also check the plug wire ends some times the don't fit tight enough and the wire going into the plug boot can become corroded and the plug won't get the right voltage for the correct spark.

 

brought a whole box at a small engine shop auction last year. got like 30 plus br9es

 

I work at an O'reilly auto parts store and I have been doing a lot of plug research and testing and found that NGK plugs have the least amount of resistantce than any other plug and I have been tryin all sorts of differnt combos on NGK plugs. If you got to a place that sells plugs, ask to look at the book for them an NGK have the best referance chart ever! I found that the BR8EG plugs which are a racing series plug run the best in my Polaris Indy 440... Check it all out, it's nice to know all the info on the plugs u are using!

Correct there is no exact cross refrence "but" polaris lists the NGK BPR series plug as an acceptable optional plug to use.

 

i always run ngk plugs they work awesome

 

It's your sled. I have ~3500 miles on the plugs that came with my sled that was made 6 years ago.

 

ngk plugs are the most worthless piece of shit plugs there are. my sled eats thruough them so quick. and it aint the sled cuz champions will last forever it seems like

It is your sled,not the plugs. NGKs are a well proven plug when used in the correct applications.

 

You might also want to check your plug caps for tight fit with the top of the spark plug and make sure the plug wires aren't corroded where the wire screws into the cap and/or coil.

Personally, I think this guy is just trolling!!
