Description

Spark plug wires are critical to consistent ignition timing and engine reliability—especially in high-RPM racing applications where factory wires fail under heat and electrical stress. The 409 Pro Racing Wire delivers superior suppression and durability with a 10.4 mm spiral core design engineered to handle sustained performance demands. This cut-to-fit kit gives you the flexibility to dial in perfect routing for your V8 engine bay while maintaining rock-solid spark delivery.
