oh ya...the 2004+ DOHC motor, the UIM sticks over the COPs/plugs in the back. You have to take the UIM off. No way around it.

Ok guys, how many miles should the original plugs be good for? My 2004 bull only hit 62000 the other day. No issues at all. Should I change them soon, or can I wait til 100K?
Thanks

My factory plugs went 120,000. My second set went 95,000...probably could have gone more, but I had to take the UIM off to get at a back COP so I figured I'd save myself the extra work.
