Moroso Universal Ignition Wire Set - Ultra 40 - Unsleeved - Straight - Pro-Boot - Blue

Moroso’s Ultra 40 ignition wire set uses a 40-ohm resistance per foot core, which helps reduce radio frequency interference while still allowing a strong spark to reach your plugs. This set is unsleeved, meaning the wire’s conductor is directly exposed, offering a clean, classic look that many builders prefer. The straight Pro-Boot design ensures a secure connection to your spark plugs and distributor cap, making installation straightforward.

These wires are built for durability and performance. The blue jacket offers a pop of color under the hood, and the Pro-Boot terminals are designed to grip tightly, preventing them from vibrating loose. While these are universal wires, they are a solid option for custom builds or when replacing worn-out original wires where a specific fitment isn't available. You'll want to measure and cut these wires to the correct length for your application to ensure a clean installation and optimal performance.
