[s-cars] The "myth" of plugs blowing out of 20vt heads.

[Taka Mizutani]

It doesn't just happen to AAN plugs.

It happened to my old A4 1.8T- plug got very loose, then blew the electrode
into little pieces that went throughout the intake manifold (don't ask me
how that happened), caused head damage to the tune of $2500.

I don't have photos, but it's well documented on the list, cost me two weeks
in a rental car as well.
