Moroso Chevrolet Big Block Ignition Wire Set - Ultra 40 - Sleeved - Non-HEI - 90 Degree - Blue

When you're rebuilding the ignition system on your Chevrolet Big Block, a solid set of spark plug wires is crucial for getting a strong spark to each cylinder. This Moroso Ultra 40 wire set is built for those applications, featuring a 7mm conductor and a durable silicone jacket that can handle the heat under the hood.

These wires come with a special sleeving that adds an extra layer of protection against heat and abrasion, which is a smart addition for big block engines that tend to run hotter. The 90-degree boots on the spark plug end make them easier to route and connect, especially in tight engine bays. They're designed for non-HEI distributors, so make sure that matches your setup. The blue color gives a clean, custom look to your engine bay.
