How to replace the spark plugs?

if you trace the wires (6) YOU'LL FIND THE PLUGS.... many times it's easier and faster to remove anything in the way than it is to do Mechanic Yoga, reach around.... seems like more work but often easier and faster. when re-inserting, turn plug COUNTER-CLOCKWISE till you feel it CLICK to verify thread allignment, then tighten by hand and finish with socket wrench (1/16th turn).
