New Spark Plugs


Recommended Posts

I have recently replaced the spark plugs. I sprayed some WD-40 on the threads of new plugs for smooth installation. They were in use for a couple of weeks (some 300 miles). Today I noticed a reddish thin dust coating on the insulation when I was treating the plugs with some dielectric grease. Should I have them tightened harder?
