There is nothing wrong with the 90915-YZZB5 filter. Some say it does not have a bypass valve, but that is not true. It has 3 oil passages at the front of the filter, covered by a rubber lip. The rubber will deflect under pressure and open up to allow the oil to bypass the filter. I actually like this better, because the oil does not pass over a dirty filter element to get to the bypass. True, it does not seem to have as much filter area as the -20004, but I don't think it will be a problem if you change your filter at <10k mile intervals. I think even the back of the filter adds capacity that the -20004 did not. The media is a fiberglass mat type. I understand Wix is now starting to use something similar. You bought a Toyota because it is a well engineered, well made product, why would you start to doubt them now? You know how may of these filters are in use right now, without any problems? Well, I can vouch for one.
