Multiple Electrode Spark Plugs Improved Engine Performance

Do multi-electrode spark plugs improve the performance of an engine ?. It is claimed that multi-electrode spark plugs can reduce carbon fouling and are more durable but may have possible performance disadvantages. This video tests spark plugs with a standard single electrode and then double, triple and quadruple electrode spark plugs. This demonstration just shows the sparking of each plug working on a tester but does not demonstrate each plug’s performance in an engine that is running continuously under load over an extended period of time. A research was carried out on the ‘Impact of spark plug number of ground electrodes on engine stability’ which tested the performance of multi-electrode spark plugs in detail.
