Why Your Engine Needs Spark Plug Heat Protection

Modern engines run hotter than ever, particularly near exhaust headers, turbochargers, and performance manifolds. Without proper heat shielding, the rubber boots covering your spark plugs can:

  • Crack or melt under extreme heat
  • Cause misfires and erratic ignition timing
  • Lead to electrical arcing and shorting
  • Shorten the lifespan of spark plug wires

By fitting spark plug heat shields or sleeves, you ensure consistent performance while preventing premature wear of crucial ignition components. A high-quality spark plug protector ensures both reliability and safety during long-term use.

Engineered for Maximum Heat Resistance

At Kool Wrap, we use high-grade materials like woven fibreglass, stitched aluminium, and ceramic-infused fibres to craft durable spark plug heat sleeves that withstand temperatures from 650°C to over 1,000°C.

Our spark plug boot covers and protectors are:

  • Universal-fit and compatible with most plug wires
  • Easy to install—just slip over the boot and wire
  • Available in multiple colours for custom setups
