Description
Product Overview
The MSD spark plug wire set is engineered for high‑performance engines that demand precise ignition timing and reliable spark delivery. Each wire incorporates a copper alloy conductor with a resistance of less than 50 ohms per foot, ensuring minimal voltage loss. A ferro‑magnetic impregnated core acts as an effective EMI choke, while forty feet of conductor is compacted into a single foot of wire to maximize suppression. The outer sleeve is a proprietary heat‑resistant compound, and stainless steel terminals feature dual crimp tabs for secure connections.
Usage
Designed for both street and track applications, this wire set excels in high‑rpm environments, turbocharged engines, and heavy‑duty trucks. It is ideal for enthusiasts seeking consistent spark under extreme heat and for mechanics replacing worn wires in daily drivers.
