Types of brake pads

Heat rating – characteristic that shows the spark plug ability to remove heat from the primer electrode tip.

Surface ignition – a spontaneous ignition of the gas mixture inside the combustion chamber from red-hot combustion chamber parts (spark plugs electrodes, valves) and big particles of the scale.

Thermal characteristics – it is a dependence of the spark plug operating temperature from engines effective power. It depends on the spark plugs design, quality of its cooling and parameters of engine operating process.

Heat cone – it s distance between primer insulator tip and it`s place of putting into cone.

Resistor – serves for suppression of RFI (Radio Frequency Interference), which arise in high-voltage car system. Provides protection of radio equipment and different electrical control systems.
