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

Moroso's Ultra 40 ignition wire set uses a 0.040-inch conductor diameter, which offers a good balance between spark energy and resistance for Chevrolet small block engines. These wires are designed to run under the headers, helping to keep them away from extreme heat and potential damage. The unsleeved construction means the conductor is directly exposed, allowing for maximum spark energy transfer to your spark plugs.

This particular set is configured for non-HEI distributors, meaning it's compatible with older points-style or external coil ignition systems. The black color offers a clean, understated look in the engine bay. Proper wire routing and secure connections are key to ensuring these wires perform as intended, delivering a strong spark for reliable combustion.
