DEI Protect-A-Wire 3/16in (5mm) x 50ft - Red

DEI is a well-known name when it comes to keeping engine components cool and protected from extreme heat. This Protect-A-Wire sleeve is a smart way to shield your valuable spark plug wires, or other electrical wiring, speedometer cables, and hoses, from the harsh under-hood environment. It's designed to prevent burning, cracking, and hardening that can happen when parts are exposed to high temperatures.

This particular sleeve is made from a high-temperature resistant glass fiber material and can handle continuous heat up to 500 degrees Fahrenheit, withstanding radiant heat up to 1200 degrees Fahrenheit. It's a 50-foot roll in a bright red color, making it easy to identify and manage. Installation is straightforward: you typically remove the distributor boot and slide the sleeve over the spark plug wire. Having a bulk spool like this on hand is great for shop use or for any project where you need to keep wiring safe from heat damage.
