SHINEHOME Spark Plug Header Boots 2500° Heat Shield Sleeve – 8-Pack for SBC/BBC/LS Engines, Blue

Overview

Meet SHINEHOME Spark Plug Header Boots—an 8-pack of blue heat shield sleeves designed to sit over spark plug boots and nearby wires. Built for hot under-hood environments, these sleeves help manage heat from headers and exhaust manifolds while keeping installation straightforward.

Made for durability, the sleeves use a dual-wall braided fiberglass sleeving with a triple-wall sewn end. They resist heat up to 2500 degrees intermittently, offering a protective layer where heat is most intense and where wiring lives closest to the exhaust.

Key benefits

• Protects boots from burn-through, hardening, and cracking in high-heat settings.

• Long enough to cover spark plug wires near headers, accommodating a range of boot styles.
