Spark Plug Hole Plug

Keep the inside of your engine clean and safe from you accidentally dropping a nut or bolt down the spark plug hole when the spark plugs are removed. It will also prevent dirt or dust from getting inside also.

These plugs are made to suit a standard 14 mm thread, so they measure a bit less than 14 mm. You can see a video here:
