That they are a little difficult to remove is why I like them so much. They do come off without having to unscrew them however. They have a spring type clip inside, so they will release. It takes a good pull and a little bit of a wiggle. Just be careful that you don't pull so hard that when they come off you end up tugging on the lead where it exits the engine. Try clamping a plug in a vise and get a feel for how much pull it takes. It's really not that much, it's just a different feel compared to the cheap clip on types.
