you're right about Bosch products, even though I like to buy 100% made in USA (parts too).

When I was 17, my uncle handed me an old, rusty ARIEL motorcycle and said: fix it and it's yours! With very limited funds, the first thing I did was to replace the spark plug with a new Bosch plug. Well, a few week later it was running, and very quickly I sold it, only to buy a used TRIUMPH. But I didn't keep it very long - I upgraded to a 4 wheel car...for safety concerns.
