Best sparkplug?

[Twostrokepower!!!]

I am running a kx85 and i was wondering which sparkplug would be the best for winter riding, i keep it in the pipe so fouling them isnt usually an issue, im running a 2.60$ NGK, is there better ones?

[twosmoke595]

i run NGK's in everything we have

i personally haven't found a better one for the price, in the winter here the bikes do lose a little power but as far as consistency its just as good, hot or cold

Ngk all the way man....their new iridium line of plugs (eix suffix) is awesome great response

I use NGK. It handles my rich mixtures well, so I like it.

  What's the real world advance over normal IW-series plugs?

  Is it really worth the price?

[oldermxr]

better burn and throttle responce iridium plugs use less ignition to fire

Yes. Better your engine is tuned the bigger the difference they make.

NGK is the best in my opinion . my bike takes a $35 spark plug 

[cnrcpla]

$35?       WOW... Is it made of gold?

[msmola2002]

nope, iridium...

Check out the size of both electrodes - super super fine.

  I bet you have a RM, I remember buying those suckers. You can,t run a diff plug either.

 yup you guessed it and RM125,   I actually started running a br8es in it and it seems to do fine .

the best plug is one that hasn't fouled,
 my bike came with a $35 dollar plug too, didn't fit under my oversized tank, so I replaced it with a shorter cheaper NGK, i'm on the third  plug since I bought the bike new in 07'. Two plugs one when I put the tank on and the other when I rebuilt the topend.
I ride it like a four stroke and run 32:1 with the pilot leaned one size
