I have found that a toilet float kit comes with a pretty little blue rubber tube, about 8 inches long, that is an exact fit for the top of a spark plug and allows you to spin a plug off or on very easily. It saves a huge amount of time in not having to wrench or ratchet in the confined space available in the engine bay.

Hope this helps someone who is frustrated with this job as I was. It really speeds up the job.
