The Design Engineering Protect-A-Wire protects your spark plug leads from the extreme heat generated by the headers or exhaust manifolds. Constructed from a Fibreglass composite material, they install in seconds and come in a range of colours.High heat protection for spark plug leadsPrevents burning, cracking, melting or hardening of the leads due to excess heatUniversal fittingCapable of withstanding radiant heat up to 500°F (260°C)Design Engineering Protect-a-wires prevent damaging heat that can cause misfiring. If the ignition leads are very close to the headers, it is still advisable to wrap the header with exhaust wrap in the problem area in addition to the Protect-A-Wires. Can be used on any hose, wire or fuel line up to 10mm diameter.Options:2 Cylinder - Contains a 7ft (2.13m) length of sleeving and 6 x high temperature heat shrink tubes8 Cylinder - Contains a 25ft (7.62m) length of sleeving and 25 x high temperature heat shrink tubesThe heat sleeving supplied in the kit can eas
