Spark plug important element by proper selection of engine, this efficiency depends on the details of the entire engine.


Convert ferric metal coating provides reliable corrosion protection. Ceramic insulator fluted form, provides better heat transfer and prevents the formation of sparks out of the zone. Copper core wonderful removes heat.

Construction features

Resistor-fluctuating energy in time of creating sparks, form the radio frequency interference. Data interference affect power stations, radio transmitters and electronic control units, including engine control unit. Usually the resistor has a monolithic structure made of graphite and glass, his task is to organize the Central electrode voltage inside the candles.
Because the resistor has a resistance, candles not equipped them with more powerful spark, as reduced energy loss in passage through the Central electrode. For this reason, most sports and racing engines use candles without a resistor. Note, however, that if the manufacturer setting of candles with resistor, then the installation can adversely without candles affect the operation of this engine.

V-shaped tip of the Central electrode-a special form of the Central electrode sends a spark to the edges, thus reducing the contact area, at the time of the sparks. Such design allows to reduce the absorption of heat electrode produced by spark ignition and increase the efficiency of the fuel-air mixture.
