If that were true, aftermarket filters would not sell well at all, nor would air filters, oil, ATF, yatta, yatta, yatta. Now, obviously, if the aftermarket filter was somehow defective, then sure, the manufacturer would have no liability.
This is why we have certifications, .. manufacturers provide specific "specifications" that oil, filters, ATF etc must meet to be acceptable for use.
As MH pointed out above (and the linked FAQ Bulletin issued by the FTC he posted describes), I'm talking about a defective aftermarket filter causing engine damage, and the car manufacturer proved it was the aftermarket filter's fault. I highly doubt a car manufacturer is going to replace an engine under warranty if an aftermarket filter failed and caused the damage. The car manufacturer would propably make you go after the filter maker, and most brand name filter makers have warranty statements for such situations. Might need to read the fine print of the car manufacturer's warranty statement to see if they talk about use of "OEM Approved" aftermarket parts with respect to warranty coverage.
If the filter was an OEM part and failed causing engine damage, then of course the car manufacturer is going to cover it all, should be no questions in that situation.
