Protect-A-Boot Silver 8pk Fits 90 Deg Plug Wir

The Protect-A-Boot Silver 8-Pack Spark Plug Boot Sleeve from Design Engineering is a braided fiberglass protective covering engineered to shield spark plug boots from extreme heat, abrasion, and electrical interference in high-performance and modified engines. This set of eight sleeves fits 90-degree plug boots and measures 6 inches in length with a 1.25-inch inner diameter, making them suitable for a wide range of V6, V8, and larger displacement engines where spark plug protection is critical.

Each sleeve is constructed from high-temperature braided fiberglass that withstands continuous exposure to underhood temperatures exceeding 400°F without degradation. The silver finish provides thermal reflectivity, helping dissipate radiant heat away from vulnerable boot components. The 6-inch length covers the full exposed portion of the boot where heat cycling, oil vapor, and vibration cause premature cracking and electrical arcing. Installation is straightforward—sleeves slide over the boot before plug wire or coil pack attachment, requiring no modification to existing ignition systems.

This product is essential for street performance builds, supercharged or turbocharged applications, vintage hot rods, and marine engines where underhood temperatures and moisture create hostile conditions for standard plastic boots. Protect-A-Boot sleeves prevent boot splitting that interrupts ignition timing and causes misfires, rough idle, and loss of power. The eight-pack quantity supplies a full set for a V8 engine or covers multiple cylinders across smaller-displacement mills, making this SKU DSN10552 a cost-effective insurance policy against ignition reliability failures.
