Moroso High-Temperature Boot Sleeves

5.0 out of 5 stars 5 Customer Reviews

Moroso high-temperature boot sleeves are designed to protect spark plug boots against excessive header and engine heat. Each sleeve features dual wall construction and are breathable to reduce the oven effect often found in high-temp sleeves. They are non-flammable and will not react to petroleum based products. These sleeves expand and stretch over regular surfaces to work with straight, 90 degree or 135 degree spark plug boots and are ideal for high performance and street use. Protect your wires!
