Those fancy smancy factory plugs should be ever lasting. Check your service invoice.

I suggest that to remove and inspect the plugs your self. If they are black, there is your problem. Check the gap and deposits and color. When ever you want to see whats going on inside the combustion chambers, look at the plugs.

It was found by many that the standard NGK BCPR6ES11's ran better than the factory plug. It was also found that a .035" spark gap worked better for some folks than the spec .039" gap.

Torque the plugs to 20 ft-lbs if you don't know the feel of things. If the 4 torx screws that hold on the DI feel loose, do not over tighen them, use some locktite blue. They all seem to have sloppy threads and having them vibrate out and disappear is not unusual.
