15 minutes of fame: Spark Plugs

Yeah, I was skeptical too. But this did not disappoint. Unless you're Dave Neptune there is a lot of new information here:

So that's what a "resistor" plug is...and looks like! Who knew the "C" in "AC Delco" and "Champion" were the same person!

This video is great. To me, spark plugs are always those little doodads that either work good, need cleaning, or tossed; never really think about what goes on inside or how their current form came to be. I sent this link to my dad who is a mechanic of 50+ years and he loved it.

Not to link spam this thread, but this showed up as one of the recommended videos when I clicked the link below:

This guy created a see through head for a Briggs and Stratton; a flat head engine similar to our A4's. Over a series of 4 videos he runs different types of fuel through it to observe the flame kernel. Just multiply by four and you have a good idea of what is turning the prop. Now all I'm thinking about is a way to 3D print a transparent head for my A4 and do videos like these.
