These caps feature a durable construction with a resistor element that ensures steady resistance and prevents interior flashover. Made with high-grade ceramic materials resistant to deterioration and small resistance variation under overload, they also boast a sturdy phenolic resin plug connector capable of withstanding extreme heat and vibration. Special rubber liners at both ends effectively prevent moisture-induced electrical leakage. NGK resistor covers are crucial for meeting noise suppression legislation in vehicles, often used in conjunction with NGK resistor spark plugs (R type) for optimal results. Despite the inclusion of resistor components, NGK products maintain performance and service life. Specifically, the LB05EMH and SD05FM models are built with tough EPDM rubber for competition and trial applications.
