Been changing spark plugs for over forty years. First motorcycles, then on both cars and motorcycles. I have never lubricated anything relating to spark plugs up to now.
Will be changing my later model Beemer with new NGK plugs when the weather warms up, as now beyond the 60,000 miles suggested spark plug change, although the vehicle is running well. There are two places for potential lubrication to enable easy service the next time - the threads and the coils that attach to the plugs.
After reviewing several of the videos, my question is should I lubricate the threads and/or coils, and what with? I have hi-temp. copper anti-seize (for threads?) and both wet and dry silicone spray (for coils?). Some have suggested NOT lubricating NGK threads. Some have suggested lubricating the coils, so they are easier to extract when lifting them off the plugs the next time, as they tend to stick.
Want to be sure I am doing it right! Intend to keep the car for as long as possible, so anticipate at least another spark plug change after this round. Thank you in advance for your feedback.
