It can be done fairly easily with a 2 foot 3/8 drive extension and a swivel spark plug socket. With this combination you can stand back at the fender and take them out and put them back in. Saves a lot of skinned knuckles and/or burnt fingers.
It's better if you use a spark plug socket with a "built in swivel" rather than a separate swivel on a regular socket.
Yup. If you're not willing to purchase and use the right tools... And:
Gently twist the spark plug wire boots to break them loose from the old plug insulators before attempting to pull the boots off the plugs. Never twist, pull or push the wires proper, only the boots.
Clean the heads (plug seats) using compressed air before removing the old plugs.
Use a drop or two of motor oil on the threads only of the new plugs. Distribute the oil evenly around the threads. A Q-tip works well.
Start new plugs by hand only. VERY important.
Torque the plugs.
Spray the insides of the plug wire boots with WD-40 before pushing them on the plugs. They'll go on much easier, seat, and come off much easier the next time.
Be gentle when wrenching on the plugs or you'll crack or break the insulators. Keep your socket straight.
Be gentle with your plug wires.
Never a problem... Of course, people don't do these things and end up messing something up...
