Moroso Chevrolet Big Block Ignition Wire Set - Ultra 40 - Unsleeved - HEI - 135 Degree - Black

This is the Moroso Ultra 40 ignition wire set, specifically made for Chevrolet big block engines using an HEI distributor. These wires are designed to handle the demands of high-performance ignition systems, ensuring a strong spark reaches your spark plugs for reliable engine operation. The unsleeved construction offers a clean, classic look while the 135-degree boot on the spark plug end makes installation easier in tight spaces.

The Ultra 40 wires feature a low resistance core, which helps deliver a more powerful spark compared to stock wires. This can lead to improved throttle response and more efficient combustion. Moroso is known for making well-built engine components, and this wire set is no exception, offering a solid option for anyone rebuilding or upgrading their big block Chevy's ignition system. The black finish provides a stealthy appearance under the hood.
