About this product
Upgrade your ignition system with the Sumax 409 Pro Race Custom-Fit Spark Plug Wire Kit. These high-performance spark plug wires deliver superior conductivity and heat resistance, ensuring optimal engine performance and longevity. Designed for both electronic and point-type ignitions, this kit offers a significant improvement over standard carbon-core wires.
Description
The Sumax 409 Pro Race spark plug wires are engineered for maximum performance and durability. Featuring a Spiro-Pro core, these wires provide up to 10 times the conductivity of standard carbon-core wires, resulting in a stronger spark and improved combustion. The extra-high-temperature silicone boots and wires offer exceptional protection, withstanding temperatures up to 600°F. This superior heat resistance prevents breakdown and ensures consistent performance even under extreme conditions. Precut to fit and with plug/coil boots and terminals already installed, the Sumax Pro Race wires simplify installation, allowing you to quickly upgrade your motorcycle's ignition system. The low resistance design of these 10.4 mm wires also ensures they run cooler and last three to four times longer than typical carbon-core wires.
