Numbered Plug Wire Marker Kit
Quickly and easily identify your cylinders with this Design Engineering numbered wire marker set! This kit allows you to mark each of your ignition spark plug wires with an easy to read, heat shrink label. The heat shrink is a 3 to 1 ratio that slides over the boot and then shrinks tightly to your plug wire. The numbers are marked in a bright white ink that is oil and chemical resistant. The heat shrink is tough enough to handle the high under hood temperatures your car sees on a daily basis.
