It's interesting to see the filter getting condemned purely on appearance. Without testing the filter's efficiency (and ability to supply the correct oil pressure and flow) - how can it be said it's not a good filter?
On the Suzuki XL-7 there is a known issue with timing chain rattle. Oddly enough, many people have found the OEM filter is best for reducing the timing chain rattle at start up. I've tried many reputable after market brands and had some horrible results with chain rattle for extended periods.
Aftermarket filters are often a case of "if it screws on, it fits". Whereas, I've found Suzuki spec different model oil filters for different engines- even though those engines could physically use the same filter. You're guaranteed the oil pressure, flow and filtering are correct spec when using the OEM filter.
It's something to think about.
No one is really condemning the OEM filter but to assume that just because it's the OEM filter, it would be the best filter you can get is a fallacy.
Keep in mind that OEMs have to manufacture at a certain price point. They can't make their filters cost too much which then affects the quality of the materials and construction.
While I agree that there are many benefits to OEM filters that outweigh the costs, some folks like me would have to be greatly inconvenienced to get my hands on them. On the contrary, I could get something like a Mobil 1 oil filter at my local auto parts store which is most likely a superior filter (it costs more too).
Lastly, consider the fact that Suzuki is not designing nor manufacturing the filter. No car manufacturer does. They simply have parts/filter manufacturers supply the filters that they label as OEM. There are many "aftermarket" filters that are identical to OEM filters because that filter maker is the one that manufactured the OEM filter in the first place.
