Spark Plug Heat Shields

Protect Your Ignition System

High-performance headers often run dangerously close to ignition wires, causing boots to melt and crack. This damage leads to arcing and power-robbing misfires. Installing spark plug heat shields is the best defense for your ignition system. Designed to slide over standard boots, these protectors reflect damaging radiant thermal energy away from sensitive components, ensuring your engine fires correctly even in tight clearances.

Constructed from materials such as basalt fiber and aluminized fiberglass, these shields withstand extreme temperatures, preventing rubber from hardening or becoming brittle. By keeping the boots cool, you ensure consistent spark delivery and engine reliability. Adding spark plug heat shields is a simple, effective upgrade that prevents burnt wires and costly replacements, ensuring your engine runs smoothly under any condition.
