Hello there, just doing the maintenace on my 04 Sportsman 600 and the kit cam with different plugs than called for. It calls for BKR7E and I have BKR7E. I understand these are consedired a hotter type.

Any recomendations

 

The Owner's Manual for my Sportsman 700 call for Champion RC7YC spark plugs.
I really like NGK plugs and find they cross-reference from the Champion as NGK6097.
All the measurements I can find reflect that they are the same size physically.

Have you tried their BKR7EIX Iridium plug? Thats what i'm running
