trust me man, the wires and plugs didnt give you any more power than stock ones wouldve...you probably had some worn/old wires and or plugs and by replacing them with those you got the car back up to where it used to be...where you got a power gain, but not any more than stock.
bosch platinum 4's are wierd on saturns...they either work great or suck ass. there have been many mixed reviews on those plugs. seems like some saturns like them and some dont.
