Setup and Installation
The MSD 31193 wire set is designed for custom installation, allowing you to tailor wire lengths to your specific engine configuration. Follow these general steps for proper assembly and installation:
- Measure and Cut Wires: Determine the required length for each spark plug wire. The set includes various lengths (e.g., 2-56”, 2-50”, 2-42”, 2-32”, Coil Wire-32”) to accommodate different engine layouts. Use the included Mini-Stripper-Crimper tool to cut the wires to the precise length needed.
- Attach Terminals: Strip the wire ends and crimp the appropriate terminals (socket-style or spark plug-style) onto the wires using the Mini-Stripper-Crimper. Ensure a secure connection for optimal conductivity.
- Install Boots: Slide the desired boots over the terminals. The boots are designed to fit snugly. In some cases, trimming a small amount from the boot or gently squeezing the internal clip with pliers may improve the fit and ensure a secure connection to the distributor cap or spark plug.
- Route Wires: Carefully route the assembled spark plug wires to avoid contact with hot engine components (like headers) or moving parts. Consider using wire looms/clamps to secure the wires and prevent damage.
- Connect to Spark Plugs and Distributor: Connect the spark plug end of each wire to its corresponding spark plug and the distributor end to the correct terminal on the distributor cap. Ensure all connections are firm and fully seated.

Operating Considerations
Once properly installed, the MSD 8.5mm Super Conductor Spark Plug Wires are designed to deliver consistent and powerful spark to your engine. Their low resistance and high-quality construction contribute to improved combustion efficiency and reliable engine operation, especially in high-performance applications. No specific operational procedures are required beyond standard engine operation.
Maintenance
To ensure the longevity and optimal performance of your spark plug wires, consider the following maintenance tips:
- Regular Inspection: Periodically inspect the wires and boots for any signs of wear, cracking, burning, or damage. Ensure all connections remain secure.
- Cleanliness: Keep the wires free from oil, grease, and dirt, which can degrade the insulation over time.
- Proper Routing: Verify that wires are still routed away from hot exhaust components and moving parts. Adjust wire looms or clamps if necessary.
Troubleshooting
While MSD Super Conductor wires are highly durable, issues can occasionally arise. Common symptoms of spark plug wire problems include engine misfires, rough idling, reduced power, or poor fuel economy.
- Misfires: If experiencing misfires, check each wire for proper connection at both the spark plug and distributor. Inspect for visible damage or arcing.
- Resistance Check: If a wire is suspected to be faulty, measure its resistance with a multimeter. Consult MSD specifications for expected resistance values.
- Heat Damage: If wires show signs of melting or burning, re-evaluate routing and consider adding heat protection sleeves or relocating wires further from heat sources.
