Now, i'm kind of curious.  How much resistance are we talking?  I went to 
the local auto parts store (the small business kind, with an old guy 
behind a counter with shelves of parts), and asked him for some "normal" 
ignition system hookup wire.  He had mostly kits of full wiring systems, 
but the stuff he had in bulk looks like stranded 14 gauge copper with 
about .120" of black rubber over it.  It measures 0.0 ohms for 5 feet, 
and I can't see anything unusual about it.  It's definitely not what I 
would condsider "performance" cable either- I've seen that stuff and it's 
not 8 cents a foot. 

So the question is: is the resistance really supposed to be in the wire 
itself, or is there a resistor moulded into the end plug perhaps? Seems 
to me that if you wanted #14 wire with a constant non-neglegible 
resistance per linear foot, it would have to be made of something other 
than copper.
