MSD 5542 Street-Fire Spark Plug Wire Set Ford 351C-460 Socket 8mm Black

The MSD 5542 Street-Fire Spark Plug Wire Set is purpose-built for Ford big block and Cleveland/Modified engines, including the 351C, 351W, 352, 390, 400, 429, and 460. Designed to work with factory socket-style distributor caps from 1965–1976, this pre-terminated, ready-to-install wire set delivers reliable performance-grade ignition at an affordable price point.

Each wire features a spiral-wound conductor wrapped in a durable 8mm silicone and synthetic jacket, providing excellent resistance to engine heat, abrasion, and tearing. Black silicone boots at each terminal protect against high exhaust temperatures, while heavy-duty terminals ensure a secure, corrosion-resistant connection at both the spark plug and distributor ends.
