Description
Reliable spark delivery is non-negotiable in high-performance racing applications, and the 409 Spiro-Pro Plug Wire Race Set delivers consistent, clean ignition timing cycle after cycle. Designed specifically for GM LS-series engines, this kit eliminates the weak points of factory wiring with a robust spiral core construction that resists electrical noise and heat degradation. Whether you’re running a naturally aspirated build or forced induction setup, these wires maintain signal integrity under sustained RPM and extreme underhood temperatures.
