I am not sure but I will let you know soon. About to hit 60K miles. I already bought the plugs, going to install them when it cools down some (Florida). That being said, it looks easy if you just take your time moving things out of the way to get to them.

If you know how to use tools, it's not that hard. Some tips that I can recall off the top of my head, mainly to give yourself a tiny bit more room to work: remove the control modules bolted on either side of the heads, remove battery completely to get to those back two cylinders, don't be afraid to unclip wire harnesses - just remember to put everything back. Don't think I had to go crazy with extensions or swivels, just that a few are pretty tight to get to. Take your time and don't smash your beer on the ground in frustration.

Ahhh...just like my '08 IS250.
I think that was about 5 hours by the book if I remember. It was a real pain.

Hoping the RC-F is easier...I'm at 58K miles now

Strange that there aren't any YouTube videos out there for the RC-F or the GS-F

I lifted mine ever so lightly. It was enough to work around. I never replaced the intake gasket either....and never had an issue in the 50K miles after

Changed my plugs a couple of years ago. I used a tutorial in one of the stickies, took a while, but wasn't bad at all. Just take your time.
