How Does a Spark Plug Connector Work and What Materials Are Typically Used?

    A Spark Plug Connector functions as the interface between the ignition coil and the spark plug. When the ignition coil generates a high-voltage current (often 12,000 to 45,000 volts), the connector transfers this current to the spark plug tip. This creates an electrical spark that ignites the air-fuel mixture in the combustion chamber. The connector must be made from insulating materials to prevent electrical leakage and must also resist heat, oil, and vibration.

    High-quality Spark Plug Connectors are often made from silicone, EPDM rubber, or thermoplastic elastomers. The internal terminals are typically brass or stainless steel to ensure conductivity and corrosion resistance. In export markets like the Middle East or Russia, where vehicles are exposed to extreme temperatures, our connectors are tested to exceed OEM specifications. B2B buyers can request samples or certification documentation for quality verification.
