8x Spark Plug Header Boots 2500?? Spark Plug Heat Shield Sleeve Wire Cover Wrap

This set of 8 spark plug header boots provides a protective heat shield sleeve and wire cover wrap for spark plug wires, shielding them from extreme underhood temperatures. These spark plug header boots are designed to fit standard spark plug wire terminals and prevent heat-related wire damage. Use these spark plug header boots as a direct replacement for worn or missing factory heat shields.

Overview

This kit includes eight spark plug header boots that serve as a spark plug heat shield sleeve and wire cover wrap, protecting your ignition wires from excessive heat. These spark plug header boots are intended for vehicles where spark plug wires run near exhaust headers or manifolds. They help prolong the life of the wire wrap and ensure consistent ignition performance in high-temperature environments.

Built For Performance

• High-temperature resistant fiberglass construction shields wires from radiant heat
• Flexible sleeve design conforms to tight routing and bends near headers
• Secure fit around spark plug boot ends prevents slippage during use
• One set of eight covers a full engine wire set for complete protection
• Lightweight and non-abrasive material does not damage adjacent hoses or wiring

On-The-Job Use

• Install over spark plug wires routed along exhaust headers in muscle cars and trucks
• Use on performance engines with close-fit header tubes to prevent wire melting
• Suitable for classic car restorations where factory heat shields are unobtainable
• Protect wire cover wraps in marine or off-road engines exposed to high heat

Specs At A Glance

Good To Know

Q: Can these spark plug header boots be used with any spark plug wire? A: Yes, these boots are sized to fit standard 7mm and 8mm spark plug wires, and they slide over the boot end easily. They are not designed for 10mm race wires without confirming inner diameter clearance.

Q: Will these boots fully cover the spark plug wire end? A: Each boot covers the terminal boot area and extends along the wire to provide a heat shield sleeve, but they do not cover the entire wire length. For full wire coverage, multiple boots per wire would be needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
