That said, if one is comfortable using a larger filter, and is willing to assume any potential failure/warranty risk, however small, then so be it. Using common sense about the larger size ie., not extreme, could increase that comfort level.
Using an oversize filter after warranty eliminates that potential drawback/disadvantage to filter choice.
But, aftermarket filters that meet spec, are no different than OEM as far as the warranty goes.
And yes, the OP's vid clearly relates to racing, not pc use.
Agreed. I believe quality aftermarket filters for the correct application are often better than whoever the OEM chooses to supply them with.
I choose Mahle or Wix whenever possible, just from all the brands I have seen these seem better quality (from a build quality point of view)
