MSD spark plug wires are manufactured to emphasize conductivity so that the there's minimal loss in voltage as electrical currents travel through them. A foot of 8.5-millimeter superconductor wire provides a mere 40 ohms of resistance, meaning the channel is relatively clear of electromagnetic interference. This same foot of wire bundles together over 40 feet worth of conductor.

The result of such dense bundling is a suppression capability--also known as "choke"--that insulates the wire and prevents EMI leakage. Less durable wires can allow radio signals to escape and interfere with your car's other electronic processes. In an age of auto-manufacturing when more and more components are driven by computers, this can represent a real hazard.

The Construction of MSD Spark Plug Wires

When it comes to the design of spark plug wires in general, materials play a key role. The makers of MSD wires use copper for its excellent conduction capabilities and tightly wind it around the wire core. They then insulate the core with a sleeve made from synthetic materials and silicone to ensure its integrity.

The extreme heat generated by your car's engine is enough to melt inferior products, which can lead to core damage and, consequently, spark plug wire failure. Whether you're purchasing universal or custom MSD wires, strength and conductivity are your two most important criteria. If you're unfamiliar with the specs involved, be sure to ask your parts dealer for more specific info.
