Edelbrock Max‑Fire Ultra‑Spark 50 spark plug wires for SBC 1978–1986 V8 HEI applications deliver low resistance and high EMI/RFI suppression for improved spark delivery. These engine‑specific sets use an 8.5mm silicone jacket to protect a Kevlar spiral core from heat, moisture and chemicals. Wires are engineered for performance engines and deliver the low ohms‑per‑foot needed when aftermarket upgrades require maximum voltage; consult the application chart for exact kit fitment.
