This listing is for one Dri Plug. You may purchase any number by selecting the quantity you need above. Depending on your cylinder engine you may need 4, 6, 8 or 12.
Why Dri Plugs? If your going to store your vehicle long term or just over the winter these plugs can give you added protection against moisture and corrosion in the cylinder walls. These plugs fit all 14mm spark plug holes which are extremely common in classic cars and boats. Dri plugs are reusable and can be dried out during the off season. They are shaped like spark plugs and serve to seal the cylinder chamber and dry it of moisture. It will help eliminate moisture accumulation caused by an open valve. The top of the dri plug can accommodate the spark plug wire.
About Dri Plugs: Dri Plugs are used by the US military for storage of vehicles and aircraft engines. They are essentially transparent moisture and gasoline resistant containers for silica gel, a dehydrating agent capable of absorbing water in an amount equal to or more than 45 % of its own weight. This gel is impregnated with anhydrous cobalt to give it a bright blue color when dry. As it takes on moisture the treated gel begins to turn violet and then pink at the saturation point.
We have a limited number of these plugs available at a starting price substantially below the 30.00 each the military pays.
Price listed is per plug. You decide how many you need!
