Protect-A-Boot Ringless Sleeves are superior protection for extreme angled plug wire boots that solve the problem of burning and cracking plug boots and wires from header and engine heat. DEI Protect-A-Boot Ringless Sleeves are uniquely designed to protect spark plug boots & wires against the harmful effects of direct and continuous heat - up to 1200F. Continued exposure to extreme heat generated from the engine block, exhaust manifold and headers can cause burn through, hardening or cracking of the spark plug wires and boots.

Titanium Protect-A-Boots(TM) XL are the latest in thermal protection technology for spark plug boot protectors. Developed from a unique material mined from lava rock stranded and woven into a proprietary weave for added durability and strength yet is pliable enough to provide a universal fit for straight or angled boots. Titanium Protect-A-Boots XL are naturally resistant to heat, chemicals, abrasions and contaminants, and are engineered to withstand temperatures up to 1800F (983C) of direct heat. High horsepower engine compartments are known for extreme heat that can put spark plug boots and wires at risk.

EXO Series Spark Plug Boots are designed to withstand extreme racing and high heat environments. The outer Exoskeleton stainless mesh prevents direct contact with the Dual layer Silica boot underneath. This combination of Silica/Air Gap and Stainless steel provides outstanding heat protection for your plug boots and wires. Available in 2, 4 and 8 packs so you can protect trouble areas or your complete wire set.

Protect-A-Boots XL Ringless solve the problem of burning and cracking plug boots and wires from header and engine heat. Protect-A-Boots are made from a high temperature resistant glass fiber material and treated with a proprietary coating, Protect-A-Boots XL Ringless provide spark plug boot and wire protection from extreme under hood heat and helps prevent burn-through, hardening and cracking of boots. For thicker boots, like MSD or Taylor's, we recommend our Protect-A-Boot Ringless Sleeves.

Titanium(TM) Protect-A-Sleeve solves the problem of burning, cracking plug wires, lines & hoses from engine & exhaust heat. DEI's Titanium Protect-A-Sleeve with LR Technology(TM) offers the best possible line sleeve protection on the market.
