DEI Fuel Rail and Injector Cover Kit for the 1997-2004 Jeep 4.0L (TJ Wrangler, XJ Cherokee, WJ Grand Cherokee), built to stop heat soak and vapor lock by shielding the fuel rail and injectors — especially the heat-prone #3 injector — from under-hood heat. Each cover is high-temperature glass fiber with a reflective aluminum outer skin over an 8mm thermal barrier between dual reflective aluminum layers, secured with integrated hook-and-loop closures.
