The NGK replacement spark plug caps are screw on. Even if your original plugs caps are not screw off, you can cut them off and screw on NGK replacements.

Dark Jedi said:I wasn't thinking about this until I went to look at it. I just replaced the coils, and the wires and caps are part of the coil itself on my bike. Not real happy with that either. That means I get to replace the coils whenever the plug wires wear out, and vice versa.
