Granatelli Hi-Perf Ignition Wire Connector Kit with Black Sleeves and Ceramic Boots for 2014-2021 GM LT1 (V8-6.2L)

Fits 2014-2021 GM vehicles equipped with the LT1 engine (V8-6.2L).

The Granatelli Hi-Perf Ignition Wire Connector Kit is engineered to resolve heat-related ignition failures common in high-performance GM LT1 applications. By utilizing ceramic boots, this kit provides a thermal barrier capable of withstanding extreme temperatures that would typically melt or degrade standard silicone connectors. This is a critical upgrade for vehicles running aftermarket headers where tight clearances lead to intense heat soak.

Each kit includes black protective sleeves to shield the wire from radiant heat and abrasion, ensuring a secure and high-conductivity link between your ignition coils and spark plugs. The ceramic construction prevents arcing and maintains ignition integrity even under the most demanding driving conditions.

• High-temperature ceramic boots resist melting in high-heat environments
• Black protective fiberglass sleeves included for additional thermal shielding
• Direct fit for 2014-2021 GM LT1 engine architecture
• Ideal for use with aftermarket headers and high-performance exhaust systems
• Provides a secure, high-conductivity connection for consistent spark delivery
