Customer Questions & Answers

  • Question: What makes the MSD 31239 Super Conductor Spark Plug Wire Set ideal for performance engines?

    Answer: The MSD 31239 Super Conductor Spark Plug Wire Set is specifically designed for high-performance applications, making it ideal for built engines and racing setups. Its 8-cylinder configuration and 90° angle ensure a perfect fit for various engine models. Made with low-resistance materials, these wires drastically reduce RFI (radio frequency interference) and improve spark delivery, leading to enhanced ignition performance. This is especially beneficial for engines that require consistent firing under extreme conditions, such as motorsport or racing scenarios.
  • Question: What materials are used in the construction of MSD 31239 spark plug wires?

    Answer: The MSD 31239 spark plug wires are constructed with high-quality silicone and solid core materials. The silicone insulation is designed to withstand high temperatures while providing excellent electrical insulation. Additionally, the wires feature a ferrite core that minimizes RFI and ensures a reliable spark discharge. This combination of materials translates into durability and performance efficiency, making these wires suitable for both street and track applications where consistent power delivery is crucial.
  • Question: Can the MSD 31239 Spark Plug Wires be used with a standard HEI cap?

    Answer: Yes, the MSD 31239 Spark Plug Wires are compatible with standard HEI (High Energy Ignition) caps. This compatibility makes it easier for enthusiasts to upgrade their ignition system without needing to change other components. Using these wires with an HEI cap ensures optimal spark transfer and efficiency. Typical scenarios involve retrofitting performance wires into classic cars or muscle cars that already utilize an HEI ignition system, providing enhanced engine performance.
  • Question: What lengths do the MSD spark plug wires come in?

    Answer: The MSD 31239 Super Conductor Spark Plug Wire Set includes wires of varying lengths tailored for specific cylinder placements. These wires are designed for easy routing within the engine bay while maintaining optimal distance from other components, preventing interference. By ensuring that each wire is the right length, this set minimizes signal loss due to excessive wire length, which is vital for maintaining engine performance in racing or high-torque driving situations.
  • Question: Are MSD 31239 wires resistant to heat and abrasion?

    Answer: Absolutely! The silicone jacket of the MSD 31239 spark plug wires is both heat and abrasion resistant. This means they can endure high engine temperatures and friction from engine components without degrading. Such resilience is crucial for performance applications where wires are exposed to tougher conditions. Whether you’re utilizing your vehicle for drag racing or on rugged terrain, these wires will maintain their integrity and performance under pressure.
  • Question: What is the resistance level of the wires in the MSD 31239 set?

    Answer: The MSD 31239 spark plug wires have a low resistance level, typically around 40 ohms per foot. This low resistance allows for minimal energy loss during spark transmission, which is essential for achieving peak ignition performance. The lower the resistance, the stronger the spark that reaches the spark plug, enhancing combustion efficiency. This is particularly important in applications where optimal engine responsiveness and power delivery are critical, such as in motorsports or customized performance vehicles.
  • Question: How do I install the MSD 31239 Spark Plug Wire Set?

    Answer: Installing the MSD 31239 Spark Plug Wire Set requires basic tools and a little mechanical knowledge. Start by removing your old wires, taking care to label them for easy reconnection. Attach the new wires to the spark plugs and the distributor or HEI cap, ensuring they are firmly seated. It's crucial to route the wires away from moving parts and hot surfaces to maintain wire longevity and performance. This installation is often undertaken during routine maintenance or a complete ignition system upgrade.
  • Question: How do these spark plug wires improve engine performance?

    Answer: The MSD 31239 Spark Plug Wires enhance engine performance mainly by improving spark delivery. By reducing resistance and RFI, they allow for a more powerful ignition spark, which leads to better fuel combustion. This results in increased horsepower, improved throttle response, and overall better engine efficiency. Enthusiasts often notice significant performance improvements during acceleration, especially when upgrading from standard wires in performance applications.
  • Question: Are these spark plug wires suitable for street use?

    Answer: Yes, while the MSD 31239 wires are designed for high-performance applications, they are perfectly suitable for street use as well. They provide excellent spark transfer and durability that benefits everyday driving conditions. Many users who participate in motorsport find that these wires perform reliably without compromising daily drivability, striking a balance between performance and functionality for both racing enthusiasts and casual drivers.
  • Question: Where can I buy the MSD 31239 Super Conductor Spark Plug Wire Set in Canada?

    Answer: You can purchase the MSD 31239 Super Conductor Spark Plug Wire Set from Ubuy in Canada.
