409 Spiro-Pro Plug Wire Race Set 135-Deg Blue

The 409 Spiro-Pro Plug Wire Race Set 135-Deg Blue is engineered for high-performance GM LS-Series engines that demand superior ignition reliability under extreme racing conditions. These wires are designed to replace standard factory sets, providing the necessary spark energy to maximize combustion efficiency in modified or high-output powerplants. Whether you are building a dedicated track car or upgrading a street machine, this kit ensures your ignition system can handle increased heat and electrical loads.

Featuring a massive 10.4 mm diameter, these wires utilize a spiral core design that balances low resistance with maximum electronic interference suppression. The blue silicone jacketing provides exceptional thermal protection, resisting temperatures that would typically degrade lesser ignition components during prolonged high-RPM operation. The 135-degree boots are specifically angled to provide optimal clearance around exhaust manifolds and headers, ensuring a secure connection to the spark plugs without risking heat damage.

This complete kit includes factory-style boots and terminals, making the installation of the 409 Spiro-Pro Plug Wire Race Set 135-Deg Blue straightforward for any LS-series enthusiast. The precision-engineered terminals ensure a positive lock on both the coil and the plug, preventing vibration-induced misfires common in competitive racing environments. By choosing this Taylor/Vertex set, you are investing in a proven ignition solution that maintains peak performance across the entire power band of your GM V8 engine.
