Spark plug Bosch or Motorcraft

newer Bosch plugs, cap, rotor (maybe 15k ago)

Recently replaced original spark plug wire set w/new Bosch; wire set, distributor cap, rotor, O2 sensor and Platinum spark plugs

I think that the recommended plug (and original equipment) is probably a Bosch Silver plug, and that is what I would probably stick to if I were you.

the car seems to run really good at the .028 with the bosch plugs

I've been researching spark plugs and i believe the oem's in Phaeton are Platinum. I am certainly going to verify that and will change mine to Iridium's. For the purpose of better power, performance, and fuel mileage.

I found a set that didnt get sent with my car for some reason when i sold it they are worth the money my idle smoothed out with the bosh compared to the autolite 63's

Changed spark plugs, wires, cap/rotor with Bosch bits (w7dtc not those crappy +4s)

I bought some of those and didn't think much of them tbh. My engine prefers NGKs for some reason. Feels smoother and more eager to rev. I noticed with the F5DPORs a 'welded on' tip which looked a bit weak

After I put them in (I was one of the first in my region to carry them and use them in my own car) I found a significant loss of power. Swapped those puppies out for some Bosch Supers and I was back to where I was before I put the Plats in.

Don't use those, they suck. The center electrode is tiny, and fouls easily. I've had problems with them, and so have others. They don't last for ****.
