BMW 528I Series How To Change Spark Plugs The Easiest Way 

great, totally agree with you, thanks for sharing and God bless you and your Family as well.

I used one. BMW has these rubber boots above the spark plugs that keep the socket from fitting. I used multiple but none fit.

you dont have to but I like to apply some to make it easier to remove in case if they are going to be there a long time.

@@JM-AUTO okay thanks for the tip!

16mm socket 6pt, thanks for sharing.
