Heat control experts, Design Engineering, Inc. (DEI),
have now produced a new version of their popular Protect-A-Boot spark plug protectors.
The new Protect-A-Boot Sleeves provides thermal protection for highly angled, oversized and rigid spark plug boots.
Why do spark plugs need thermal protection?
Excessive heat generated from an engine block, exhaust system or turbo can easily affect a vehicle’s ignition system. Spark plug leads and boots can harden, burn or crack, leading to arching, engine misfire or even complete ignition system failure.
DEI has produced thermal protection boots for spark plugs for many years, but the new sleeves are pliable to enable them to be fitted to plug boots with a sharp or 90° angle, to fit over rigid boots as found on classic engines and to fit over non-removable boots on the end of ceramic or silicone ignition leads. Their flexible construction also makes them suitable for many coil-on-plug applications where the connector is stepped or otherwise varies in diameter and petrol powered classic military vehicles with radio suppression on the connectors.
Protect-A-Boot Sleeves are made from a tightly woven, high temperature resistantant, glass fibre material resistant to direct and continuous heat – up to 650°C - enabling them to protect against heat emitted by turbocharged engines.
Protect-A-Boot Sleeves are currently available in silver in either a two-pack (part #010551) or eight-pack (part #010552) package.
