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. This is a link to the research article: https://www.sciencedirect.com/science...

Have you tried multi-electrode spark plugs in your vehicle ?. If so, how did they perform in your engine and how would you compare them with the standard single electrode plugs in regards to engine performance and fuel economy etc. ?. Give your thoughts in the comment section below.
