About this part

Product Details

This pack includes four Vibrant 3/4-inch diameter spark plug boot insulators in black. These are designed to slip over your spark plug wires right at the connection to the boot, offering a layer of protection against high engine temperatures. Keeping your spark plug wires cool helps prolong their life and ensures consistent ignition performance.

Crafted from braided fiberglass, these sleeves can handle temperatures up to 1200 degrees Fahrenheit (650 degrees Celsius). Because they require minimal clearance from hot engine components, they can be installed in tight spaces without needing extra room. This makes them a practical addition for many engine builds where heat management is a concern.
