Iv used those cheap lighters that use a quick spark to ignite the gas, but after a couple weeks they die out. How are the ones in engines so reliable and last for so long?
Furthermore, how can they fire at JUST the right time, thousands of times a second?
Thanks in advance

Sparks plugs are connected to the computer of modern cars and the computer times everything in the engine so that they spark at just the right time. They are designed to last a long time.
