SUMAX Spark Plug Wires - Black - FXR 77035

If your ignition system is running on worn carbon-core wires, you're losing voltage before it ever reaches the plugs—and that means poor combustion, rough idle, and wasted fuel economy. SUMAX Spark Plug Wires deliver 10 times the conductivity of standard wires through their Spiro-Pro core, ensuring maximum voltage transfer to your cylinders while running significantly cooler under load. Built from extra-high-temperature silicone and pre-terminated for bolt-on installation, these wires last three to four times longer than conventional options, making them the smart upgrade for any serious build.
