In principle, I agree with you, particularly if the vehicle is still under warranty. If your engine develops an issue and you've installed an Acme filter, you've provided Hyundai a point they can argue to deny your warranty claim. We purchased our car from CarMax. They did an oil/filter change before our purchase; within 3 days of buying it, the car was at a Hyundai dealer for, you guessed it, an oil change. I just wanted to make sure the proper oil and filter were installed.
That said, automobile, heavy equipment and heavy truck manufacturers make cars and commercial trucks & equipment, not filters. I was VP Marketing for a global filter manufacturer before retiring a few years ago. We manufactured and sold filters under our own brands as well as private labeled filters
for other filter companies and OEMs. If you visited one of our plants, you'd see our brands alongside CAT, Deere, WIX, Fleetguard, and many, many other brands.
Hyundai filters are
possibly manufactured by Hyundai Mobis, but they are likely provided by an outside filter supplier. Most vehicle manufacturers don't view manufacturing their own filters as economically feasible or necessary.
If a filter manufacturer wants to make an
aftermarket equivalent to an OE filter, they have to test the OE filter extensively, and then design and create a filter which meets or exceeds the OE filter's performance. If they don't and there are engine failures attributable to the filter, they'll end up with expensive warranty claims or a lawsuit. (Commercial engines, for instance, are NOT inexpensive.)
All this said, cartridge filters like this are inexpensive.
There's no good reason to not buy replacements from your Hyundai dealer. At best you'll save a buck or two. The point of my post was just to help out the OP, who was requesting
aftermarket filter numbers.
P.S., spin on or cartridge makes absolutely no difference. The filtration media's efficiency and capacity, along with the integrity of the design and manufacture, are what matter. Sorry for the long post!
