New Wix filter for Subaru 2.5 FB motor

[sopususer]

I saw this on a new product release from Wix they've released the 57830 as a filter for the new 2.5 FB Subaru motors in the Forrester. It doesn't list the filter for the Legacy yet, but I can't see why it would not work since it is the same motor. I may have to give this one a try for the wife's 2013 Legacy.

Also listed as a Napa Gold

WIX 57830

Is this filter equivalent to the MC-FL 820s and FL-500s?

no it has a higher 20+psi bypass setting

NO.

The FL820 has a 16 PSI bypass vs the Fl500S which has an 8 lb bypass.

The WIX 57830 has a 28PSI bypass rating.

Both OEM filters are speced out at 23.2 psi.

also I posted on this back in june when they were ""available""
but no one had any.

^^^ My local Napa warehouse is showing the Napa gold in stock.

Part Number: FIL 7830 at $5.98ea

I remember searching back in June when you posted it and came up dry around here. Forgot all about it until now.

why does subaru's tend to have high psi bypasses?

 

[flstffxe]

Theory is the high volume that the oil pump is able to put out.

Even the small 9mm oil pump does almost 11-12GPM, the larger 10, 11, and 12mm pumps can do 16+ GPM and around 20 GPM once you start going past redline on modded engines.

Since we are talking PSID (pressure in v. out Delta) does the bypass really figure in? The pump and subsequent filter output is hiughly restricted by the engine - it's NOT a wide open system post filter by any reason. IIRC, the high bypass is only a concern for turbo oiling, not NA. I would not run a flat gasket filter on this engine as i've had leaks or weeping using various aftermarket units. Is the new wix a flat gasket or a P gasket?

I would stick with Subaru filters to be honest.

I see WIX lists the beta ratio in the link in the first post as:

2/20/75=26/>50/>50

Which means:
2=26: 50% @ 26 microns
20=>50: 95% @ >50 microns
75=>50: 98.7% @ >50 micron.

Not the most efficient filter I've seen. 95% @ 50 microns isn't that great. Looks like it's made to flow in order to handle the Subaru high volume oil pumps.

Understatement IMHO. I looked at that two, but I am not sure how much faith to put into those beta ratio numbers on their site.

What about filtration efficiency of 15208AA130 and 15208AA160?
