First of all killer, killer find on the WIX, it's one of the best over the counter filters on the market.

Those are 100% real WIX, They do have stickers on them plus it has the scan bar as well as the proper date format on the top of the filter and the box is correct. Right crimps, right anti drainback valve cover. And other than the fact there is almost zero market for fake WIX this is a great find for those who want a great filter.

Here is won from Napa auto parts in the US cut open and it's the same as the WIX 51515 filter. NAPA gold = WIX.



Again WIX are not all fully painted logos, most of their new ones in the black cans will have stickers.



WIX 51515






(A: Nominal rating usually means the filter can capture a given percentage of particles of a stated size (e.g. 50% * 10 micron). Absolute rating is the smallest typical particle size retained by a filter media at 98+% efficiency. This is also referred to as the Beta=75 or 98.67% efficiency rating. For additional information about nominal and absolute micron ratings)

But wix used the multi pass testing vs single pass so their math is a bit different.

Here is a little WIX secret

They have not updated online the ratings on there filters over a year ago they change up their filter media. Here's a example of how WIX math works.

51040 OLD (still almost as good as a Baldwin)
50% at 15 microns
95% at 31 microns
Nominal 21

51040 NEW (killer performance for a over the counter filter)
50% at 6 microns
95% at 20 microns
Nominal 21

WIX are superior to any over the counter filter sold there that is not a fleet style filter period.
