DEI Wire Markers 8pc Set Numbered 1-8 - Black

Keeping track of your wiring, especially in the engine bay, can get complicated. These DEI wire markers are a straightforward way to label your spark plug wires or other critical connections from 1 to 8. They're made from high-temperature, Mil Spec black heat shrink tubing that can handle the heat under the hood, staying flexible even in extreme temperatures. The 3-to-1 shrink ratio means they'll slide easily over most wire boots and then shrink down tight to the wire for a clean, professional look.

The numbers are printed in a high-visibility white ink that resists oil and chemicals, so they'll stay legible. They meet Mil Spec DTL-23053/5C and are flame retardant, offering a more durable and professional alternative to simple tape or plastic ties. You can install them easily with a heat gun, applying heat between 120 to 180 degrees Fahrenheit.
