Description
The Sumax 409 Pro Race Spark Plug Wires are engineered for maximum performance and durability. Featuring a Spiro-Pro core, these 10.4 mm wires offer up to 10 times the conductivity of standard carbon-core wires, resulting in a hotter spark and improved combustion. The extra-high-temperature silicone boots and wires provide exceptional protection up to 600°F, safeguarding against heat damage. Their low resistance properties help them run cooler and last three to four times longer than conventional carbon-core wires. Designed for electronic ignitions, these wires also deliver excellent results on point-type ignition systems. Installation is straightforward thanks to the pre-cut lengths and pre-installed plug/coil boots and terminals. These black spark plug wires are a stylish and functional upgrade for any high-performance engine. Made in the USA.
