From Copper Alloy Conductors to Heavy Duty Boots...
the MSD 8.5mm wire is engineered to outperform any and all spark plug wires. Where OEM wires typically have over 3,000 ohms per foot of resistance, MSD 8.5mm wires have less than 50 ohms! That means more spark energy to the spark gap and more horsepower to the pavement. MSD 8.5mm wires are test fit and equipped with factory-fit boots along with exclusive MSD Dual Crimp Terminals for bulletproof reliability.
