All ignition systems are not created equal but as a generalization performance coils are not needed on a stock engine. If you feel they are worthwhile consider the cost/benefit as I don't see a good value. Performance coils can be beneficial if the engine is modified, more likely if engine is boosted bet even then it is not a sure thing. There are also mixed reviews about the longevity.

I suggest 'reading' the plugs and see if a change in heat range might be in order. Best way to improve mileage is often adjusting the foot on the gas pedal.
