Had the plugs changed today.... Came out without any problems (Whew)
Heard many horror stories on plug breakage.

 

Just had mine tuned up today, too. New plugs, tested the coils, compression test, and general tune-up. One plug had lost part of the curved spark thing-a-majig. Small piece of it stuck on top of the piston. Scope was used to look into the cylinder, but nothing damaged.

Really runs great now! Quite spendy, though. With diagnostics and new plugs, total was $565.00. 93,000+ miles.

 

Besides the plugs, they did a compression test, did a coils, coolant flush and fuel Injectors cleaned, full multi-point inspection (all looks great) fluids topped off.
Unfortunately, my bill was $750.
