[TR] TR3 Coil

Not to defend Bosch or Lucas, but just to relay what was said to me by a
British car specialist many years ago, these companies (he was referring to
Lucas) manufacture the parts that are ordered by their customers - cost and
quality, frequently design. Lucas made parts for airplanes where reliability
is pretty important, his point was that Lucas' bad rap was ill deserved.
Same could be for Bosch. Just saying...

In defense of Bosch - I have had good results with most Bosch products.
Granted, that style of fuse with the exposed element (I think the body was
ceramic, not plastic) can easily corrode and cause a failed connection but
those were made by many manufacturers (used them on my Fiats and VWs) and
was just a poor design.

My Bosch ignition wires that I bought in the 90s finally failed and I saw on
their website that they guarantee them for life.  Fortunately, I had saved
the receipt (don't we all) and indeed they promptly sent me a refund almost
20 years after the original purchase.

My favorite quote from that website:  "Spain (next best thing to Germany)".
Perhaps the guys in Madrid should adopt that for their tourism campaigns.
