Now you know the size, I went to my local car parts store and grabbed a few generic, fit any car plugs.

While I was under there replacing the plug behind the starter motor, I checked the others. Glad I did. Ended up replacing two or three that afternoon.

Thankfully none replaced were behind the engine mounts.
