Yes, there are several good videos on the utube to view the process of a spark plug change on the n20 or n26 engines. But, I'd like to offer just a couple small but important TIPS/Suggestions.
1. Use the correct and proper thin wall spark plug socket. I used the following...and so happy that I made the purchase!!
14mm 12 Point Spark Plug Swivel Socket - CTA 1061
Part #: CTA-1061
2. Use compressed air (from a can or air compressor) to blow the spark plug area prior to working on engine. Once the coil has been removed...and before touching the spark plug, blow some compressed air down the area making certain that it is clean.
3. Do
NOT use anti-seize compound on the spark plug threads. BMW has a TSB that using it might cause a fault code or short.
4.
DO use a proper torque ratchet wrench. This is NO time to guess by "feel".
Good luck with your spark plug change project!!
