Moroso Chevrolet Big Block Ignition Wire Set - Ultra 40 - Unsleeved - HEI - Over Valve - Red

Moroso's Ultra 40 wire set uses a solid copper conductor with a resistance of only 40 ohms per foot, which is a notable improvement over standard wires. This lower resistance helps ensure a strong spark reaches your spark plugs, contributing to more efficient combustion in your Chevrolet big block engine. These wires are designed for HEI distributors and route over the valve covers, making them a practical choice for many builds.

The unsleeved construction means these wires have a more direct feel and appearance, often favored in custom builds where aesthetics and function are both important. The vibrant red color adds a touch of style under the hood. Moroso has been a trusted name in performance parts for a long time, and this wire set reflects their focus on delivering well-built components for serious engine applications.
