The first I did a spark plug change, I had myself the mouth of a sailor since it was so hard to get into the passenger's side...
But take your time, do it one-by-one. You don't need an "adaptor" Just make sure you have yourself a 5/8" spark plug deep socket, 3/8" extension (or whatever the size of socket and ratchet it will be)...you'll be fine.
Stupid me pulled all the wires out...almost panicked because I didn't know the order of the wires...but if you look on the coil-pack, you'll see it.
lol...What spark plugs are you planning on installing?
