Your not going to gain much as far as plugs go......however you can go an iridium.... but its not going to do much but last longer and be harder to foul.

I run the Iridium in my LT250r. Worth the money for a 2-stroke, but I wouldnt spend the extra money for one for a 4-stroke.
 
The only thing you will feel by a "better" spark plug is a little more throttle response.. easier starting. The iridium plugs are nice because yoiu can run a richer or leaner mixture and the coil will still be able to fire the plug as it requires less amperage to jump the gap so you get less miss fires.
