Cheapest oe i can find around here is 55 bucks. NO WAY!!! in the tech section there's this:

$11 spark plug wire set
Aaron, mailto:nitrusmr2@yahoo.com
Being the cheap guy I am (hey, I'm supporting 4 project cars) I found/made a very inexpensive set of wires for my 931. Are they Magnacores? no, but do they work? yes. When I purchased my new distributor cap I noticed the connectors looked very similar to pre-73 General Motors stuff. I also purchased a new set of plugs so I would not have to contend with the threaded ends of the current plugs. At this point I had a cap with standard connectors and plugs with standard ends, so I headed to NAPA and shopped for pre-made wires by the inch. I think I bought 1 12" length, 2 18" lengths, and 1 24" length. I also bought a different 12" wire to use as a coil wire (bring you old wires with you for comparison purposes). If I was really concerned about maximizing performance on minimum budget I would have bought a cut-to-length set of Mallory's or MSD wires and attached my own ends. I hope this will save you guys a few bucks.

But when I called napa and asked for pre-made wires and the guy acted like I was speaking some sort of alien language and had no idea what I was talking about.

anyone out there know of anything else I could try. I really can't see paying more than $20 or so on a wireset.

That's the cheapest I've found for magnecore wires. Far less than OEM.

There's always the DIY stuff, but I am not sure exactly what tools you need etc, never made my own.

But if it's a 924, you don't need those, just these http://www.pelicanparts.com/cgi-bin/smart/more_info.cgi?pn=10-8533-617-M106&catalog_description=Ignition%20Wire%20Set%2C%20924%20%281977-82%29%2C%20Each

Or just go to napa... hell i think I paid like... $20 for my plug wires at napa, works just fine.

Yep, just use cheap universal plug wires and plugs with normal ends. Just make sure you pay attention to where the resistor is in the ignition system.

We finally ran away screaming from the Magnecors after too many races lost due to the wires popping off the plugs. We now use Kingsborn, and they're bulletproof (not to mention cheaper) thanks to factory ends.

why do you need to pay attention to where the resistor is?

Not sure about that, but FYI Dan (ideola) now carries the Kingsborn wires, IIRC...

Stock wires have resistors built into the ends and the plugs don't.

With the aftermarket, generic wires, the resistors need to be in the plugs (which also have the proper terminal tops on them)

So instead of ordering the NGK BP6ES plugs, you order the NGK BPR6ES plugs, etc.

As for the terminal tops of the plugs, if you look at the stock plugs on your car, you'll see the top is smaller and threaded when compared to other plugs you might have seen. On some plugs there is a threaded cap that fits on here that you can remove to fit the stock style ends.

When you switch to more generic wires, you'll need plugs with the more common style end on them and resistors built into them. Just something to check before you leave the store as some don't have the removable caps, etc.

Typically, the generic wires are on a wall display near the counter or in the ignition wire section.

Here's a couple of links:

http://www.napaonline.com/Search/Results.aspx?Ntt=Spark+Plug+Wire|Single%20Plug%20wire&Ntk=Keyword|Keyword&N=0

Rock Auto has a Wholesale closeout on stock wires for $22, otherwise the cheapest are $40 and that doesn't include shipping. They also have generic wires for $.85/ea on closeout. Search under Extras for Spark Plug Wires.

The resistors are needed to cut down on high voltage interference getting picked up in your electronics or even with the ignition system itself. I believe on the older cars without electronic ignition, they aren't truly needed, except to remove noise from the radio.
