Has anyone had this done as of yet? I’m due, and curious to see what others have been charged for the service. Thanks!

Not yet. I have purchased a socket wrench but don't know if it will work yet. These cars seem to require a specialized and very thin wrench. the spark plug is 14mm and the diameter of the socket must be less than 18mm. I also found some NGKs that seem to match our engines but there is not a lot of info out there, I may just go to the dealer parts department to be sure.
