Resistive Spark Plugs

Fotos-ImagensWith the appearance of onboard electronics in vehicles, NGK has developed in the late 1970s, resistive spark plugs that have a ceramic resistor, able to attenuate electromagnetic interference caused by ignition system. This interference is extremely detrimental to vehicle electronic systems such as:

– Electronic fuel injection;
– Sound system;
– Antitheft system (alarms, blockers and trackers);
– Automatic gear shift with electronic control;
– Traction and stability electronic control;
– Air Bag and ABS Systems.
– CAN Network;
– Air conditioning with electronic control;
