Moroso Chevrolet Small Block Ignition Wire Set - Ultra 40 - Unsleeved - HEI - Under Header - Blue

This is the Moroso Ultra 40 ignition wire set, specifically made for Chevrolet Small Block engines using an HEI distributor. If you're running your wires under the headers, this set is designed to help keep them protected and routed cleanly. The blue, unsleeved wires offer a straightforward look and direct connection to your spark plugs and distributor cap.

Moroso designed these Ultra 40 wires with a focus on reliable spark delivery. They feature a 40-ohm resistance per foot, which helps ensure a strong spark signal without causing excessive electrical noise that could interfere with other vehicle electronics. The under-header routing means they're built to handle the heat radiating from your exhaust manifolds, keeping them from getting brittle or melting over time. This set is a solid option if you're looking for a direct replacement that's built for a specific under-header installation on your Chevy small block.
