I am coming up on 70,000 miles and figured I would go ahead and change the spark plugs a little early than the OEM recommend since it is such an easy job. Having never changed plugs before (never had a car that needed them) I am curious on how the condition faired after an unknown number of miles (bought at 55k). The plugs say Volvo which makes me think they are newer since older plugs I have seen all said FoMoCo but who knows!
The plugs look pretty consistent from one to another with some having a small bit of yellowing on the ceramic portion right after the threads. Seems like normal wear. no?
