Spark Plug Wires

Hey everyone, I purchased new NGK spark plug wires with the boot attached. They are 5ohm resistance. How do I get the wire off the end that attaches to the coil pack. I was told I could change them. To me it does not look like it just unscrews like the spark plug end.

Thanks in advance.

They don't unscrew and you shouldn't. Just replace the caps. If need be, you can supplement the existing wire w/ plain old black reinforced fuel line. Some heat shrink on both ends too ... but obviously not needed.
