Drake's high-performance 8mm Ignition Wires are made with a Ni-Cr (nickel-chromium) spiral-wound inner core, silicone boots and outer jacket, brass distributor terminals, and stainless steel spark plug terminals. Printed with the repeating Ford logo, they also come marked for correct cylinder installation for classic 289-302 engines ensuring a clean, professional-looking engine compartment. Note: these will also fit late Model 302 High Output and 351W Engines, however, due to a different firing order some wire tags will not correspond with the correct length and will need to be removed.
