Project: Spark Plug Holder
A spark plug holder can be quite helpful when changing engine spark plugs. It keeps the plugs in one place so you won't lose them in your shop or garage. Race teams use holders when they do not have time to deal with the plug packaging – the holder makes a fast changeover possible.
