300m coils are good for around 40k (which is about the "norm" for most oem coils)
airFS in your case I would still recommend a wire upgrade (taylors, FordRacing or any other good wire) stay away from MSD wires.... unless they have changed lately their wires only work with the older design coil... or their coil.
As for plugs stock plats gapped at .060 should do great.
