These are supplied as a material kit with a drawing and instructions for you to make your own spark plugs! They are not difficult to make and you can vary the "reach" to some extent to suit your particular installation. Whilst these plugs will run in most applications they are particularly suitable for slower running stationary engines which may have a tendency to oil- up plugs. Each kit includes plans and construction notes together with sufficient material to produce TWO plugs! Please note that you will also require a high temperature adhesive such as JB Weld.
