I have my wife do it. My hands are to big. She reaches in gets the plug out and a new one in about a minute. I learned this little trick after spending an hour trying. Oh, she great at changing turn signal bulbs too.
I use a 1/2 inch breaker bar w/ a 3/8 drive adapter for the traditional 5/8 park plug socket to loosen. This combo is just the right length and depth to reach all the plugs. The I use use a 3/8 air ratchet w/ Snap-on flex extenstion to to fully R&R the plugs. I use a 1/2 torque wrench w/ 1/2 to 3/8 adapter and short impact swivel to re-torque. Last set-up is much tighter and AIR hoses do have to be moved/worked around to get good angle.
