NGK Resistor Covers are designed to reduce electro magnetic interference and radio frequency interference which can interfere with electronic ignition components causing misfires and poor engine performance. Resistor covers are manufactured using extremely durable Phenolic Resinand EPDM rubber. Ceramic resistors are used to ensure optimum performance and reliability. Resistor covers must withstand extreme heat, vibration, prevent flash over and must be waterproof to perform. NGK spark plugs superior design ensures optimal service life and performance.
