Product Details

These Granatelli ignition wires are built with a 7mm silicone jacket and a fiberglass conductor, designed to handle the demands of your 1977-1979 Ford truck, van, or SUV with a 5.8L or 6.6L V8 engine. They replace your old, worn-out wires to ensure a strong, consistent spark gets to each cylinder, which is crucial for smooth running and reliable power delivery.

When your original spark plug wires get old, they can crack, corrode, or lose their ability to insulate, leading to misfires, rough idling, and a noticeable drop in performance. Granatelli designed these wires to offer a solid upgrade over stock, helping to restore lost power and improve fuel efficiency by making sure each spark plug fires cleanly and at the right time. The silicone construction helps resist heat and abrasion, common issues in the engine bay, while the fiberglass core provides a stable path for the electrical current.

This set is made to fit your specific Ford V8 application, making installation straightforward. Replacing your ignition wires is a practical maintenance step that can make a real difference in how your engine runs, especially on older vehicles.
