sparkplugs/ wires/ col packs will not give you HP I would onloy replace your coil pack if it is gong south on you. for wires I went with the ford racing ones I have been happy with them and for plugs I have autolite platinums. if you are stock I would first get an intake from CTA or wait for D Davis to get his out and a performance exaust. for starters.
OOH and WELCOME to CEG and the Zetec section....
