Features
- Materials: These heat shields are constructed from double-layer woven fiberglass sleeves capable of withstanding intermittent temperatures up to 2500F. Advanced thermal insulation effectively blocks radiant heat from exhaust manifolds and intake manifolds, preventing spark plug wire damage and performance degradation.
- Universal Compatibility: Each 6.1-inch sleeve features a 1.37-inch inner diameter, fitting most standard spark plug boot sizes. Its flexible design seamlessly adapts to 90-degree, 45-degree, and straight boot configurations, making it widely applicable across various engine systems.
- Thermal Protection: The sleeve creates a protective barrier, preventing the spark plug wire boot from scorching, hardening, or cracking due to engine overheating. This protective mechanism helps maintain insulation performance, reduces misfire risk, and extends the lifespan of ignition system components.
- Easy Installation: Slip-on installation requires no tools or modifications. Simply insert the sewn end of the sleeve over the spark plug boot, then push the open end downward until fully covered. The snug-fit design ensures the cover remains securely positioned during engine operation.
- Engine Compatibility: Compatible with most classic engines, including Chevrolet small-block/big-block, Ford, Chrysler, and other V8 configurations. Particularly suitable for engines with narrow exhaust clearances, effectively isolating spark plug wires from exposure to high temperatures in the exhaust manifold.
