Thermo-Tec Cool-It Plug Wire Sleeves-4 Pack Red

This unique spark plug and ignition wire protector comes in four sporty colors; red, blue, black and natural. These dual-purpose sleeves enhance performance, reduce misfires, extend plug wire life and will not react with petroleum products.

The double-wall construction keeps the wire and boot cooler in a high-temperature engine. Its universal size fits most boots, is easy to install and - most importantly - is non-flammable. Cool-It Plug Wire Sleeves can be used in any high-temperature environment from street vehicles to motor homes. Sleeves are available in packs of 4 & 6.
