Oh I know - a few years ago I changed out the blower pulley and tune on my 03 Lightning with a modular motor and I was required to put in a colder plug. It took me two days, off and on, to change all 8 plugs. Fortunately I didn't break any either and I made sure to apply a complete coating of anti-seize on the threads of all the new ones. The back cylinders were back under the cowl and out of sight - I tied the coil pack screws to my finger with a piece of thread because I knew if I ever fumbled one back there I would have no chance of ever finding and retrieving it.
