PRODUCT DESCRIPTION
The Titanium Protect-A-Sleeve solves the problem of burnt and cracked spark plug wires, lines and hoses caused by engine and exhaust heat.
DEI's Titanium Protect-A-Sleeve with LR™ Technology offers the best line protection on the market. Developed specifically for any extremely high-temperature application, this titanium sleeve protects wires and lines when exposed to direct heat up to 1800°F (980°C) or radiant heat up to 2500°F (1320°C). Thanks to DEI's patented LR™ Technology, this high-temp sleeve provides superior thermal protection for street vehicles or racing engines, protecting fuel and oil lines, spark plugs, and electrical wires from direct or radiant heat under the hood. Water and heat resistant, it is also ideal for ATV/UTV, motorcycle, personal watercraft, snowmobile and marine use.
The 1/2" I.D. sleeves accommodate many of today's larger diameter spark plug wires, protecting them from exhaust manifold heat. Titanium Protect-A-Sleeve is also available in 1" and 2" diameters.
The 0.5" I.D. x 4ft package includes ten (10) 18mm x 1.5" black heat shrink tubes for spark plug wires.
The 1" I.D. x 4ft package includes two (2) 50mm x 3" black heat shrink tubes for spark plug wires.
