Dealer quoted me $480 for the spark plug change out, which is part of 60K service. That includes OEM plugs at I think $22/each. So it's about 2.5 hours labor by their book. I'm also looking at DIY - looks like at a minimum would need to pull the battery and possibly more and need a variety of socket extensions, etc. Anybody done this?

Yeah I saw the ISF DIY, thanks. I guess RCF owners are not big on spark plug DIY or maybe very few have reached the 60K service point.

If I end up doing it I will be sure to post something on the gotchas of the job.

biggest difference is the control modules on top of the valve covers. They're on top of the engine in the IS F. They'll have to move somehow, and might end up being a lot of unplugging to get the harness out of the way. I am not far from this with the GS F. It has over 50k miles on it now.
