Spark plug heat shield sleeve / boot wrap designed to protect spark plug wires from extreme under-hood heat and extend component life. Key benefits Broad compatibility: fits a wide range of car models, including everyday vehicles, racing cars, and modified builds. Ideal wherever spark plug wires run close to exhaust headers, turbochargers, or other high-temperature sources. Simple, tool-free installation: flexible sleeve design slips on quickly for fast replacement or retrofit without additional tools or complicated procedures. Durable, heat-resistant construction: made from heat-resistant materials that resist wear and tear and maintain protection under repeated thermal stress. Reliable wire protection and engine stability: shields spark plug wires from radiant and conductive heat, helping prevent heat-related misfires and maintaining consistent engine performance. What it does for you Reduces risk of heat damage to spark plug wires and boots, lowering the chance of ignition problems and costly diagnostic time. Prolongs wire and boot life by minimizing exposure to high temperatures, abrasion, and environmental wear. Keeps modified and high-performance engines running reliably under increased thermal loads. Practical applications Race and track cars: protect ignition wires near headers, turbo inlets, and other high-heat components during high-load operation. Modified street vehicles: safeguard wires after engine swaps, header upgrades, or turbo installations that change under-hood thermal dynamics. Routine maintenance and repair: use as a direct replacement for worn boot sleeves or as preventive protection during engine tune-ups. Key attributes Function: heat shielding for spark plug wires and boots. Compatibility: broad — suitable for standard, racing, and modified vehicles. Material: heat-resistant construction for durability and wear resistance. Performance: reduces heat transfer to wires, supporting reliable ignition and engine performance. Easy to fit, robust in service, and effective at reducing heat-related ignition issues — a practical protective sleeve for any vehicle with heat-sensitive spark plug wiring.
