Moroso Chevrolet Big Block Ignition Wire Set - Ultra 40 - Unsleeved - Non-HEI - Under Header - Black

Moroso is well-known for making performance parts for racing and street applications. This Ultra 40 ignition wire set is built for Chevrolet Big Block engines that don't use an HEI distributor. The wires are designed to run under the headers, which can help keep them away from excessive heat and looking cleaner.

These wires feature a 40-ohm resistance per foot, which helps reduce radio frequency interference while still allowing a strong spark to reach your spark plugs. The unsleeved construction means the wire core is directly exposed, which can be beneficial for certain custom setups where space is tight or a specific look is desired. The black color offers a clean, classic appearance under the hood.
