Moin you love, my fatter has now 66.6k km and wanted to ask quite nicely which spark plugs I need for the E63 650i from 2009. I found at ebay NGK 8 stk in set, have data balanced ebay has given green light. Nevertheless, there is so small bitsl paranoid and rather ask again. And how long does an experienced screwdriver need for the pure change? Have now bitsl researched and yet found some topics where I could read out that this would not be so easy to do. i my model. Greetings
