Not very clear on how/why to use the 17mm plug lead wrench tool. And a warning not to pull on the lead with your hand would be wise. Also, I think it's a good idea to blow out the spark plug wells with compressed air before removing the plugs. Dirt can accumulate there and can fall into the cylinder when the plug is removed.
Lacking tutorial. No part numbers. No Hands On View of What’s Actually Happening. No Explanation of the angled wrench required to disconnect spark plug leads. Plugs in video most likely under/Over Torqued.
