14-23 GM L83 5.3L/L86 6.2L Hi-Perf Coil-Near-Plug Wire Conn Kit w/Ylw Jacket/Blk Sleeve - Granatelli Motor Sports

GRANATELLI EXTREME-HEAT GEN V IGNITION

THE YELLOW GETS NOTICED. THE BLACK FIRE SLEEVE DOES THE HARD WORK.

The Granatelli 28-5362HTYB combines yellow high-temperature silicone jacketing with black protective fire sleeves and Granatelli’s patented 0-Ohm ignition technology for GM Gen V L83 5.3L and L86 6.2L truck and SUV engines.

This high-heat configuration is designed for builders who want the visibility of a yellow performance wire while adding another layer of protection around areas exposed to headers, exhaust manifolds and increased under-hood temperatures.

DUAL-LAYER HEAT PROTECTION

YELLOW HIGH-TEMP JACKET + BLACK FIRE SLEEVE

A high-temperature ignition package for Gen V EcoTec3 builds where standard wire protection may not be enough.

Made for Engine Bays Where Heat Is No Longer Stock

Headers, turbocharger systems and other performance modifications can significantly change the thermal environment around the spark plug wires.

The 28-5362HTYB adds a black fire sleeve over the yellow high-temperature wire construction, helping protect the ignition connection while retaining the correct Gen V truck-specific geometry.
