I cannot figure how to change the 2 back plugs on the passengers side. What do I need to remove? I've looked at old posts and haven't found anything helpful. Thanks.

Bump. I have replaced 6 of 8 plugs.. just trying to figure out what NOT to remove... like this inverter. Thanks guys.

If you don't have 125k miles just let them ride and have a beer.

I guess not too many people changed spark plugs themselves on 600

Sorry we can't be more help. I did a DIY write-up on the 460, but no idea on the 600. It does indeed look cramped. I suggest you subscribe to Alldatadiy. It will give you a step by step how-to for about 15-20 dollars per year.
