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

GRANATELLI EXTREME-HEAT GEN V IGNITION

WHEN YOUR HEADERS MOVE THE HEAT CLOSER, MOVE THE PROTECTION UP A LEVEL.

The Granatelli 28-5362HTRB pairs red high-temperature silicone jacketing with black protective fire sleeves and Granatelli 0-Ohm conductor technology for GM Gen V L83 5.3L and L86 6.2L truck/SUV applications.

This version is aimed squarely at modified EcoTec3 platforms where headers, forced induction or other engine-bay changes increase radiant heat around the spark plug connections.

RED HIGH-TEMP / BLACK FIRE SLEEVE

BUILT FOR MODIFIED GEN V TRUCKS

A purpose-built Gen V wire configuration with an added thermal barrier for demanding performance environments.

Built Around More Than Just Engine Displacement

A 5.3L or 6.2L badge alone does not determine spark plug wire fitment. The 5362 Series is specifically configured for the ignition architecture used by the Gen V EcoTec3 L83 and L86 truck engines.

That application-specific geometry combines with the black fire sleeve to provide cleaner routing and added protection in high-temperature builds.
