Spark plug change 2002 C32 113K miles last change unknown
I have 113,800K miles and in the last 2562 miles I averaged 18.8 with combined city/hwy driving
Spent 2 hours and it should have been more like 1 hour...
Pulled one side at a time. It took a lot of torque to get them out and my first thought was these plugs must be original.
The passenger side had several oily threads on some of the plugs, pretty consistent on the deposits with a reddish-brown color.
Installed NGK IFR6D10 and didn't replace any wires or coils. Nothing feels different after the change so as far as I feel its a job well done

The next task to tackle will be the value covers. Maybe lol
