Help! Changing spark plugs on e60 n54 engine
Hey fellow Bimmers, I'm getting ready to change out the spark plugs on my engine as I type this message.... Do I need to disconnect the battery before I do? All the threads and videos I've found don't say to so I want to make sure. Don't want to if I don't have to. I don't plan on starting up my engine in the middle of it.
