polaris 700 spark plugs

[Xtremist]

does anyone know what type (#) of spark plug is safe to run in a 2006 iq rmk 700 ??? does need something specific or what..... cause i know that in my CR 500 i asked a dealer what type to run and they wanted me to run a 40 dollar rasce plug and i found out that theres one very similar thats like 3 dollars so yeah. any info asap would be great
