Is it just me, or are there really no options for plug wires for an E30 below like.. $100?

Can anybody explain to me why?

Prick tax?

They are expensive, but on the other hand the OEM wires almost never need to be replaced. I have nearly 200,000 miles each on several old BMWs and the plug wires are all still in great shape.

Is there anything that would keep someone from putting a "normal" plug wire on the car for testing purposes to help diagnose a misfire prior to buying the car?

Or are these special BMW wires made from unicorn hairs?

Try hitting the junkyard, our plug wires for our challenge car and my DD e30 were both well used junkyard items, and are still working great.

For testing purposes, I don't think you'd have any problems using a generic plug wire from your junk box.

Here's something I've done in the past that may be faster and easier - if you have a timing light, try clipping it to each wire to see if the light has a good strong and regular flash for every cylinder.
