Please don't kid yourself... Do you honestly believe that GM, Ford, and Chrysler (whoever they are, these days) has their own plants manufacturing AC/Delco, Motorcraft, and Mopar parts--especially something like oil/air/fuel filters, fluids, shocks, or batteries? They don't even build their own transmissions anymore, much less the fluids/filters that go in them.
I have my vehicles serviced at the appropriate dealers with OEM components, but that is strictly a matter of warranty and other documentation purposes. I have no delusions that the AC/Delco oil/air/fuel filters on my truck or Suburban were made in a GM plant, or that the Dex-cruel coolant or Dex-rot tranny fluid was either. My truck is a diesel, and it is advertised (badged) as having an Allison transmission--not a GM transmission. It's not even a "secret"--it's an advertised selling-point.

Follow Ups:
If you buy the filters specified by the auto manufacturer, you can reasonably assume that the filter specifications and performance were considered in the design of the lubrication system. It's also likely that those filters were used in developing and testing the engine.
That doesn't mean they are necessarily better than what you can find on the aftermarket, but it's a safe choice.
No one spent more money on research and development than the makers who tested to engines/oiling systems. They are not going to go with X if Y is clearly better. Good enough is good enough. I say this as an engine builder of 34 years who has never earned a W-2 doing anything else.
I just don't want people to be mis-led by slick advertising that their vehicles will last longer or perform better by spending 50-100% more on things like filters.
Sounds similar to Audio Cables!!!
I got your original intent and completely agree. If... doing my own oil changes (really don't anymore) I mostly buy OEM filters for the same reason.
Auto makers are squeezing far more HP/CI than used to be the case. Oiling systems, filters and all are even more critical. Why bother taking a chance.
I did not state anything about the car makers manufacturing their own filters. I stated that these are the ones they recommend.
Does anyone really believe that they would deliberately recommend an inferior filter and then warranty engines/transmissions/etc.?
And do not even get me started on the K&N snake oil air filters that do more harm than good...
...various manufacturers "recommend" certain "brands" of products--usually their own branded products, but may have "endorsement" deals too. If your owner's manual recommends Michelin tires, Gates belts, Bosch spark plugs, or Mobil 1 oil, it's because they got paid to.
In reality, it's all about meeting the manufacturer's specifications. Attempting to deviate/modify, then you had better just know what you are doing. And some brands (like K&N that you mentioned) can be more hype than anything else--but you get a sticker to put in your window.
I've got a small collection of vehicles--5 of them considered to be "exotics" by many. Part of their value (and reliability) are the folders full of every dealer-documented service from Day 1. They (and my dog) have more detailed "medical histories" than I do.
That's not to say that back when my cousin and I were running cars on the track, we complied--it was "anything goes". Need one more run for the night, and you know the bearings are shot at this point?--I've put 90-120W gear lube in the oil to make that run--we already knew we had to tear it down the next day anyways--only now we had a check to help pay for it.

Except the spark plug thing. Stick with ONLY what the manufacturer recommends. This is assuming that the ignition system has not been modified via MSD or some other stuff for racing. I have seen over the years GM and Chrysler vehicles run into many problems (flooding, no start, misfires) due to using Bosch plugs because Auto-Zone sold them claiming how much better they are than Delco or Champion.
And in my racing days I would have done the same thing with the oil. If its blown run it till it goes up in flames, lol.
they have a contract with someone to make the filter for them TO THEIR SPECIFICATIONS. Then if it's a good auto company they will have a legal contract for this and the auto company will have someone test them in a laboratory or they will farm it out to someone who tests them.
One deviation and it's law suit time and they know this. One of the few times the legal system really works.
The only problem with this is finding a place that sells them at a reasonable cost, the dealer will soak you. This is probably why so many buy Fram at Walmart.
