What should i use to remove the wire plugs?

Iv had a promblem romoving the wires they seem to be really tight on there and cant seem to take them out can any one give me any ways on how to take them out or should i buy the Pliers for removing plug wires?

If you are putting new wires on the car then the plier method is ok, just don't bend the metal wire protectors as you will need them for the new wires. If you plan to reuse them then don't use pliers. You should try twisting them back and forth and then pulling them off. When you put them back on use dielectric grease in the boots they will make the plug wires come off much easier next time and will also seal the boots and keep the water out.

koo thanks for the help.
