Spent $50+ on a set of Bosch spark Plug wires a few years ago. Last week
the distributor side metal connector came off when I was removing it.
Looking through the "Lifetime Warranty" I found that the first requirement
was that I spend another $50+ on a new set then send the old set to Bosch
and wait with fingers crossed while they decide whether or not to give me a
refund. Deciding to fix it myself (as Bosch likely intended I decide) I
snipped off the mangled portion of the wire (about an inch) and crimped the
old connector back on. I plugged it back in and it seems to be working fine.
BUT....
        I have done some fooling around with things electronic and I know that
there are some applications where (for wierd electronic reasons) the length
of a wire is critical in the sense that the length of a radio antenna is
critical (EXACTLY "X" length for "this" frequency, EXACTLY "Y" length for
"that" frequency. No more and no less.). "Wrong" lengths will work but not
as well as correct lengths because the voltage phase is out of synch with
the current phase and feedback from the gizmo will fubar the Benzer which in
turn will cause the resonance of .........
        I have no idea if any of this applies to spark plug wires and things do
seem to be working fine but I just thought I would ask the Gurus out there.
