HEI Spark Plug Wires Cadillac 331 365 390 429 472 500 Buick Nailhead 400 401 425

Dragon Fire spark plug wires were created to deliver extreme performance with long-term reliability. Featuring a Kevlar core with a High Performance spiral wound coated Nichrome (NiCr) (5:1) alloy conductor. With an impressive turn ratio of 100:1, lowering the wire resistance to 500 ohms per foot. The conductor is protected with a high dielectric strength co-polymer compound coating to help eliminate voltage leaks and Radio/Electromagnetic Frequency Interference (RFI/EMI). The wire is then coated again in a highly durable silicone and EPDM sleeve. All terminals are protected by extra thick silicone boots to ensure optimal spark delivery and long service life. Heat Rated to 600 F. Dragon Fire spark plug wires are a great alternative to high resistance factory OEM or cheap imitation performance spark plug wires. These spark plug wires are specially designed as a direct replacement for your old worn factory spark plug wires. *Be sure to check the Fitment Guide to confirm this is the correct part before purchase*
