DEI’s LS Engine Coil Pack Heat Shield eliminates the need to relocate coil packs and prevents premature coil failure due to overheating. Easy-to-use precut shields install under the coil bracket, reducing the radiant heat to the coils from the engine and exhaust. They work with factory and aftermarket coils and brackets. Made from semi-Ridged shield made from double sided aluminum & high temperature foam core, the shields provide insulation and extend coil life. Sold in pairs, the shields resist radiant heat up to 1,350 degrees Fahrenheit. Not recommended for LS7 engines. $38.36
