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

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.

Reinforced lateral electrode-electrode prevents The gap under the influence of high pressure and temperature change.
