Wix for fuel on the 7.3, but Ford OEM(Motorcraft FL-1995(A) ) on the oil filter. Never an issue.

I have 115,000km on my 2022 LM2 Silverado. So far it's been great, but some people have experienced serious issues on older ones. Gm is constantly improving this little motor. Lessons I've learned myself or through several forums and family members with the same motors:\n\n- Fuel additives seem to get better mpg and less regens \n- Only available oils are amsoil, mobil 1 and OEM. (Amsoil isn't dexos certified though)\n- Oil changes are pricey compared to gas, cheap compared to bigger diesels. I pay $250 CAD \n- Known to crack radiators (top right side) as well as water pump leaks. \n- Many people tend to replace the MAP sensor or clean it after a while to make it run smoother, it's a cheap part. \n- Doesn't seem to burn oil, but mine is consuming a little coolant lately (I suspect radiator).\n- The factory fuel filter is 5 micron but Wix makes a 2 micron replacement. Cheap and easy to do yourself. I pay around $50 CAD\n- Everyone online thinks they have blow by, they don't, just have a lot of crankcase pressure\n- Mine seems to misfire when started in weather colder than -15C for about a minute until warm. \n- A10 trans is smooth but has the odd rough downshift, I also follow the severe service interval table and change fluids with amsoil and new gm filter \n- Def consumption is never an issue other than towing. If towing anything heavy bring a jug or two. It will go into limp mode when you run out.
Pros: better mpg, less regens
Cons: pricey oil changes, radiator cracks
Vehicle:
Chevrolet Silverado

You may want to get your fuel filter changed if it hasn't in a while, in case it's old and let something past that it shouldn't.
I have a wix fuel filter
Vehicle:
Toyota
248k miles on my 3.0 TDi. Change the fuel filter every 20,000 miles.
Pros: fuel filter change
I just swapped the fuel filter in my 97. Got a wix filter at O'Reilly's for less than 30 bucks. I believe it's the same filter for the 03, but if not they still make them and they're very similar. It should have two ports on one side, and one on the other in the direction of flow.
Pros: cheap, easy to install
Bosch is not as good as it used to be because they want to get into the DIY market. As far as their fuel filters, I do not think you will go wrong.
Pros: fuel filters are okay
Cons: not as good as it used to be
So I changed the fuel filter carefully and was disappointed that it didn't seem to improve.
Cons: didn't seem to improve
Vehicle:
Volkswagen Golf
Just a heads up guys, do not buy these filters, my truck shut down from fuel starvation. I had put these in at maybe 2000 miles ago in my almost new 2022 with 18k miles.
Cons: fuel starvation, truck shut down
Mileage: 3218 km
