Anyone done a second change of plugs? Had a guy do mine a few years back and 2 or 3 broke. Are they any better the next time or just as prone to break? (2008 just before the new design).

They were supposedly redesigned to prevent breakage, but you can always swap them for a 1-piece plug if you're concerned.

 

Well, I went ahead and tried the plug change myself this time. Could likely do it in an hour if I hurried (but I didn't!). None broke. Check engine misfire light off and runs like new. 300,000 kms. Should be good to 450,00 now!

And I definitely think it could be done in an hour. It took me about 1h 45m, but much of that time was spent trying to figure out how to maneuver myself to get to the back plugs, looking for socket extensions, etc. Most dealer charge about 4 hours labor for this job and there is simply no justifying that.
