Design Engineering (Dei) 10501 Spark Plug Boot Heat Sleeve

Protect-A-Boots provide the ultimate protection for spark plug boots and wires from extreme temperatures generated by vehicle exhaust headers and manifolds. Made from a high temperature resistant fiberglass composite material and double wall construction. Protect-A-Boots prevent burning, hardening and cracking that could lead to engine misfire and damage. If ignition wires are touching or close to exhaust headers we recommend the added protection of wrapping the headers with DEI exhaust wrap in the problem area in addition to installing Protect-A-Boots.
