COP's and wires.

Car has 73K miles and about 10K with the KB. It's giving me wierd hesitation problems during low RPM's when you give it some pedal. Goes away after 2,500 RPMs or if you back of the gas and ease into it until 2,500 RPMs. Wideband shows a lean condition. I figured I would start with fuel filter and plugs and might as well do the wires since they are originals. Then if it continues I'd go to the tuner.
Question is, what wires are people using. I know Granatelli makes some but that's not an option for me. I don't want cheapo autozones or anthing. Any issues with particular brands? Should I just stick with Ford stuff? Suggestions welcome.
Thanks,
Steve

Alright, this stuff is new to me. Any links to said plasma booster? or other info. I was just assuming that I could buy the wires, which i thought would have the COPs on them, and then just plug and play. IDK?
