I picked up an unterminated set of 10mm Magnecore plug wires for a good deal. Spark plug ends are ready to go but I need to cut and crimp on another set of ends for my AEM coils (yes these wires are long enough).

Problem is... I can't find any tool that can crimp a 10mm spark plug wire. Anyone know of something that will work without costing more than another custom set of wires?

 

Not sure for the 10mm wires you're using, but the last time I had to crimp 8.5mm MSD wires, I borrowed one of these tools from a local guy: https://www.summitracing.com/parts/m...SABEgJfwfD_BwE

That tool can only crimp up to 8.5mm, but the dies are replaceable, so perhaps they sell dies for the 10mm wires?

 

I have yet to find a crimper with a 10mm die available, unfortunately, although there are hundreds that can do 8.5mm. I'm hoping with this thread someone can tell me a brand that still worked at 10mm

 

Exactly what I use in my shop. The key to getting a good crimp is stripping the wire to the correct length and making sure it is centered in the tool.

 

Ah cool, the description says they go up to 8.5mm but if you say they work that's exactly what I needed to know. Those things are pricy but I'm happy to invest in a good tool. Thanks!
