I find that very interesting and can only assume you have not done the same type of experiments or looked for the same things. To have contrary findings would mean your experimentation was done with some type of emulator, not a spark gap IMO. There is no substitute for a real spark gap. A zener string for example with yield opposite effects in some cases. With regard to spark plug erosion, that is due to spark power. If kept just below a certain threshold that is easily controlled. I found with my system, at the voltage I use, and with a capacitor greater than 2.5µF, metal would strip from the soft iron electrodes on the test machine. Just below that value it is reduced by a factor of 100 which is partly why I am using the common size of 2.2µF. It's not a linear process as it takes a certain threshold power to become excessively damaging. With inductive ignitions the erosion is due to the arc welder effect and the higher energy across the gap. Fred

Fortunately everyone is entitled to their own opinion and clearly our experience doesnt align with yours as there are many statements made in your 'corrections' which are completely contrary to our findings.
