Moroso Chevrolet Small Block (Sprint Car) Ignition Wire Set - Ultra 40 - Unsleeved - HEI - Black

If you're building or rebuilding a Chevrolet small block engine for sprint car racing, getting the ignition system dialed in is crucial. This Moroso Ultra 40 ignition wire set is specifically made for HEI distributors and features an unsleeved, black finish. These wires are designed to handle the demands of high-performance racing applications, ensuring a strong spark reaches your plugs.

Moroso's Ultra 40 wires use a low resistance conductor to help deliver a powerful spark, which is essential for consistent combustion and maximum power output. The unsleeved construction means they are more flexible and easier to route in tight engine bays, common in sprint car chassis. The black color offers a clean, understated look under the hood.
