MAGNUM Spark Plug Wires - Blue - FLST 3041B

Reliable spark delivery is non-negotiable in high-performance ignition systems, and factory wires often fall short under sustained heat and high voltage demands. The MAGNUM Spark Plug Wires eliminate common failure points—cross-firing, signal degradation, and heat-related insulation breakdown—with purpose-built construction designed specifically for Harley-Davidson applications. If you're running modern H-D ignition systems or building a custom setup, these wires deliver the clean, consistent spark your engine demands.
