I didn't notice any discrete resistor in the spark plug cap. My wires say 'Bosch - 7mm - Silicone High Temperature' on them. Does this sound right for 'real' Porsche wires?
Yup. The ends unscrew. There are very German-esqe crimped ends on the
wires with threads about the same size as the top post of a spark plug.
If we could replicate the crimped threaded posts then we could use
inexpensive generic non-resistor American wires and reuse the connector
at the distributor and the one at the spark plug.
Desperate for one wire, I spent a couple of hours once prying the crimped ends off. Then crimped them onto a bright yellow wire.
You have a page in your tech tips discussing spark plug wires. There is mention of replicating the screw terminals that attach to the spark plug connectors. Those screw terminals are available from Porsche, part number 911 609 310 00. I hope this is useful!

The crimp on terminals with the threaded ends on them are supposed to be
available from Wurth. Their web site is at: www.wurthusa.com.
thought about using the old spark plug connectors with some non-resistor
wires from someone like Moroso. What I'd really like to do is find a source
for the spark plug connectors that are used on the Nology plug wires.
Nology wasn't exactly very helpful when I called to ask them about getting just the plug end connectors.
The exact number of meters is something I don't know, but you get a economic
deal at Norbert Nysar
They have pre-manufactured ignition wire sets for 110,- Euro, so there's no point in trying to fix them yourself. Making them yourself would require the crimping tools, and the M3 inserts, plus some experience in doing it just right.
If you want to reuse the ignition plugs, you need to thoroughly check for oxidation and corrosion, breaks and dirt. They should have 3 kOhm distorsion suppressor resistance which in time sometimes becomes 10 to 15kOhm . This is obviously not good. Everything above 5kOhm needs to be considered bad.
Or you can just take a complete set, which costs already 400,- Euro. It save the work and you into the 100% sure direction :)
