All you need is a mirror, one of the extendable magnet, sparkplug boot puller, sparkplug socket, 4 inch extension, universal joint, another 4 inch extension, and a 3/8 ratchet, and some patience. It takes me no longer than 5 minutes to do, but I already know what to do. You will need to mirror and the magnet if you drop anything. Other than that, set up the socket with the socket and extension, then the universal joint, then the extension.
You may not need the sp boot puller to take the sparkplug wire out, but just in case it will come in handy. It is worth the pain and aggravation. Just take your time and be patient. The first time will definitely take awhile to do.
