BRISK NAR12YS spark plug

Spark plugs with small diameter silver centre electrode, suitable mainly for LPG and CNG fuelled engines and racing engines.

The use of gaseous fuel significantly saves users' money and is more environmentally friendly. Brisk Tábor a.s. places great emphasis on ecology and therefore developed a special range of spark plugs SILVER, which has been used for many years by customers from all over the world. The design of the spark plugs eliminates specific problems caused by the different properties of LPG and CNG fuel from the original fitting when running on petrol. The high thermal conductivity of silver compensates for the increase in thermal stress without the need to change the thermal value of the spark plugs and perfectly covers the requirements of the engine even when running on gasoline. The electrode shape and smaller electrode spacing reduces the voltage requirement supplied by the ignition system. The open spark gap does not prevent the flame front from spreading and ensures perfect combustion of the mixture, which is also advantageous for the use of SILVER series spark plugs for racing engines.
