About this product
Upgrade your motorcycle's ignition system with the Sumax Custom-Fit Spark Plug Wire Kit. These high-performance wires deliver superior conductivity and heat resistance, ensuring optimal engine performance and longevity. The kit includes everything needed for a hassle-free installation.
Description
The Sumax Custom-Fit Spark Plug Wire Kit is engineered for both electronic and point-type ignitions, offering versatile compatibility. The Spiro-Pro core provides up to 10 times the conductivity of standard carbon-core wires, resulting in a stronger, more consistent spark. This enhanced conductivity translates to improved throttle response, increased fuel efficiency, and reduced emissions. The extra-high-temperature silicone boots and wires protect up to 600°F, preventing heat-related failures and ensuring reliable performance even under extreme conditions. These 8 mm wires boast low resistance, allowing them to run cooler and last three to four times longer than traditional carbon-core wires. Precut to the ideal length of 21-1/2" (54.5 cm) and with plug/coil boots and terminals pre-installed, the Sumax kit simplifies installation, saving you time and effort. Made in the USA, these designer plug wire sets come in distinctive, highly visible colors, adding a touch of style to your engine bay.
