yea if you dont have the original tool, i think it would be kinda hard to get it out. IDK i always use the tool that came with the quad.

Spark plugs are only supposed to be put in snug, should always be easy to get out.
If not, someone went crazy on it for no reason :P
The head is only aluminum after all.

From the 05 Manual:
Spark Plug 17ft-lb

the only reason i can think it would be snug is that you got moisture under cap and it rusted itself in there.

If you use a socket, you may have to grind it down on the outside to fit in the hole.

Soak it down with pb blaster and let it set overnight then try it again. It sounds like it siezed up in the head from heat and moisture. One of ours did that and this is how I got it out.
