Racing spark plugs
Racing spark plugs are characterized by the presence of a platinum coating on the central electrode, which ensures a more constant spark production of the spark plug throughout its useful life, even in difficult conditions.
Being based on a very thin central electrode, the required voltage is very low thus ensuring optimal combustion.
Spark plugs for racing engines must withstand particularly intense stresses. During a race, the speed often exceeds 15,000 rpm.
The temperature and pressure values are so high, and the vibrations in the combustion chamber so intense that a conventional ground electrode could break or melt. For this reason, Racing spark plugs are often designed with specially created ground electrodes, and the extreme shape with an annular shaped ground electrode. The spark flows from the center electrode to the annular shaped ground electrode.
