Product Details

When you're working on a hot engine, keeping your spark plug wires safe from heat damage is key. This Protect-A-Wire from DEI is a well-built sleeve designed to go over your spark plug wires, shielding them from the intense temperatures found under the hood. It helps prevent the wires from burning, cracking, or hardening, which can lead to misfires or electrical issues.

This sleeve is made from 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, which is great for keeping on hand in the shop or for larger projects where you might need to protect more than just spark plug wires – it works well for speedometer cables and hoses too.

Installing it is straightforward; you typically slide it over the wire after removing the distributor boot. Having a good supply of this on hand means you're always ready to protect sensitive wiring during your build or repair.
