Help wanted to investigate some issues

Afaik, the oil filter is the one maintenance part where the difference between OEM and pattern part is the biggest. There have been numerous test and dissections of various oil filters, all of them concluding that there are no filters as good as the original, with the same quality of both the full-flow element and the by-pass element, and with a by-pass valve in addition to the check valve. Some even have only one filtering element, iirc.

Edit: Just checked a thread on LCOOL, where they found that a filter sold cheaply as genuine, actually contains only one very flimsy single layer of paper filter and a check valve, nothing else. Stole a pic from there:

That is shocking are the crap ones counterfeit , or are the toyo dealers selling them as economy filters .

AFAIK if you get a genuine Toyota oil filter from Roughtrax or Toyota it’s far superior to anything else on the market. The difference can be felt in the weight. I’m guessing the cheapies get sold on eBay and the like. It’s not even as if they are a dear item in the first place.
