2015 Mercedes S63 AMG spark plug replacement, borescope gap and indexing

come along as i swap the spark plugs on my 2015 AMG S63 mercedes benz. its my first time doing this and i run into some trouble but in the end it all works out. do this at your own risk!!! if you are not patient, detail oriented and technically savvy I would not recommend you try this on such a motor. it not to discourage you but it can go wrong...do not skip steps. for more info on tools i usd the youtube channel ‪@ExoticCarDIY‬ ...his video is much shorter and i learned from him that i can do this on my own. good luck.
