Ultra 40 Plug Wire Set - Black Unsleeved

The MOROSO Ultra 40 Plug Wire Set - Black Unsleeved is specifically designed for V8 engines that require straight plug boots and HEI or socket-style distributor connections. This wire set is ideal for street engines, racing applications, restoration projects, and hot rod builds where reliability and straightforward installation are essential.

Featuring a spiral core construction with an 8.65 mm diameter, this wire set is engineered to deliver consistent spark delivery while minimizing electromagnetic interference. The spiral core design helps reduce capacitive load on the ignition system, which is critical for V8 engines where multiple cylinders fire in rapid succession. The cut-to-fit design allows installers to measure and trim wires to their specific engine compartment configuration, enhancing heat management around the engine block.

With straight plug boots that connect directly to spark plug terminals and a HEI or socket-style connection at the distributor, this wire set ensures compatibility with various V8 ignition systems. The unsleeved black configuration maintains a clean engine bay appearance, making it a practical choice for those looking to enhance their vehicle's performance and aesthetics.
