Upgrade ignition performance and appearance with the Taylor/VERTEX 74258 Spiro-Pro spark plug wire set. Designed for small block Ford engines, this kit features an 8 mm spiral-core construction that helps provide reliable spark energy while reducing electromagnetic interference. The red wire jacket adds a clean, performance-oriented look under the hood while offering durable protection for regular street and performance applications.
The Taylor/VERTEX Spiro-Pro set includes 135-degree spark plug boots and HEI-style terminals for a secure connection at the distributor and spark plugs. The angled boots help support proper wire routing and clearance around the engine, making this set well suited for compatible Ford applications, including 1980-and-newer Ford vehicles and Mustang models.
