8.5mm Black Wire Set 135 Degree Boots

The 8.5mm Black Wire Set 135 Degree Boots by TOP STREET PERFORMANCE is a complete spark plug wire assembly engineered for GM GenV LT-series engines. This kit delivers reliable ignition signal transfer from your coil pack to each spark plug, ensuring consistent firing and smooth engine operation. Designed as a direct factory-style replacement, this wire set maintains OEM performance standards while offering the durability required for both street and performance applications.

At 8.5mm diameter, the spiral core construction minimizes electromagnetic interference and capacitive loss, promoting clean voltage delivery across the ignition spectrum. The black outer jacket provides UV and heat resistance, protecting the conductive core from degradation under the harsh underhood environment. Factory-style 135-degree boots ensure a secure, proper-fitting connection at both the coil terminals and spark plug ends, preventing arc-over and maintaining airtight seals that prevent moisture ingress and corrosion.

This wire set is ideal for owners restoring ignition systems on GenV LT engines—including those in Chevrolet Corvettes, Camaros, and Silverados. Installation is straightforward, requiring no special tools or modification; simply disconnect the old wires and route the new set following factory harness paths. Whether you're addressing worn factory wires, upgrading after engine work, or seeking reliable OEM-spec performance, the 8.5mm Black Wire Set 135 Degree Boots delivers the quality and fit you expect from a purpose-built replacement.
