NGK LKAR9BI-10 Iridium Spark Plug

LKAR9BI-10 NGK Iridium spark plug represent the highest-quality technological solution. They have an iridium-alloy tip on the middle electrode. It is welded on in a special process using a laser. The precious metal iridium is one of the world's hardest metals. It starts melting at a temperature of 2450°C and is very resistant to spark erosion. Through its use the service life is doubled on average in comparison to standard spark plugs. In addition the precious metal allows the middle electrode to be designed significantly thinner with a thickness of 0.6 mm. These measures reduce the ignition voltage requirement considerably and contribute to improving the spread of the flame front in the combustion chamber.

Main advantages of NGK Iridium spark plugs

- the best ignitability avoids fouling in all driving conditions
- the special design of the ground electrode and the central ensures that they are completely eliminated the possible misfires. Furthermore lowering the level of unburned hydrocarbons Iridium spark plugs protect the catalyst and safeguard the environment
- more ready and progressive acceleration that increase driving pleasure
- safe ignitions homogeneous combustion and engine performance are the result of a modern technology that reduces fuel consumption
- the optimized shape of the electrode reduces the voltage required for the ignition
