Motorcraft platinums (original plugs that came on the car), or Autolite coppers.These are the best running plugs for our cars. Dont bother with iridium plugs, you will see zero differences from running a copper plug vs an iridium/platinum plug.
Motocraft (Oiriginal coil pack that came with the car). Stay away from any non motorcraft coil pack, aftermarket coilpacks are utter crap due to terrible reliability and lifespan issues.
Air and oil filters:
-Either the K&N air filter one or a regular paper filter replacement will be sufficient.
-As for the oil filter, Mobile 1, Motorcraft, K&N, Royal Purple, etc. Stay away from FRAM filters.
-Motorcraft filter is a great choice
-The powerstop combo kit is what i would go with
