Nothing was mentioned about applying spark plug boot release. A small amount of dielectric grease applied to the inside of the plug and coil boots will help the boots slide onto the terminals without putting unseating pressure against the wire. It will also help prevent spark jump at the boot, especially in dirty or wet conditions. If you are careful not to get it on the terminal themselves it might help. It also helps to put a thin coat on the plug wire just above the boot, so you can slide the boot up the wire more readily. Plug boots should not be trimmed.
