Yep, like BassCliff says. The wires can be removed by cutting the existing epoxy away with a knife. I also used a dental pick to get further down in the recess the wire disappears into, there's epoxy down in there too and I couldn't pull the wire out until I'd dug out further down. Just be careful, keep at it and they will eventually just pull straight out.
When inserting the new ones, put a bead of high temp RTV around the wire about 1/2 inch from the end before you push the cable in. That'll help keep the wire fixed in position then finish up with a small bead around the top where the wire enters the coil body.
The wire just pushes down on the spike in the recess, it's not threaded like the plug caps.
