Moroso 78-15 Harley-Davidson Universal Ultra 40 Wire Set - Red

This Moroso Ultra 40 wire set comes with 8 feet of 7mm wire, which you can cut to length for a custom fit on your 1978-2015 Harley-Davidson motorcycle. The set includes four 90-degree spark plug boots and four straight spark plug boots, giving you options for routing and connection. Moroso uses a high-dielectric strength silicone jacket and a fiberglass-reinforced conductor with a resistance of only 40 ohms per foot, which helps ensure a strong spark to your plugs.

The red silicone jacket is not only vibrant but also offers good resistance to heat and abrasion, keeping your ignition system running reliably. These wires are designed to handle the demands of a motorcycle engine, providing a solid connection and efficient energy transfer from the coil to the spark plug. You'll need to cut these wires to the correct length for your specific application and attach the boots, so keep that in mind during installation.
