Best filter for Subaru engines is Purolator PL14460 with 23 psid and filtration efficiency 99.9%: http://www.purolatorautofilters.net/resources/Popup/Pages/PartDetailPopup.aspx?partnum=pl14460

p.s. I suppose, ADBV doesn't need on FB engines with top mounted oil filter.

 

unless it's a new product from purolator they have changed their marketing specs. to 20-25 from previous 16 or whatever it was. My guess, without changing actual release valve. You on the other hand must be a troll or marketer.

Oil filters for new Subaru engines (FB).

Original (Tokyo Roki) filters (23 psid, thickness can 0.44mm):

- 15208AA160 (slim): 2.76x 3.41, 1092 cm2

I have found some non-original synthetic (with advanced filtration efficiency) filters (I looked only models with height more than 3”):

1) AMSOIL (11-17 psid, 9-11gpm, 98.7% at 20u, 99% at 25u, thikness can 0.55mm):

3) Wix/Napa (8-11 psid, 9-11gpm, 50% at 20u) , thickness can 0.35mm

51356xp/41356 Platinum 2.68x3.40

51334XP/41334 Platinum 3.25x3.19

 

And models of non-synthetic filters:

51064 2.98 x 3.23 16 psi

51568 3.23x4.072 16 psi

51344 3.24x4.07

57712 : 2.68x2.58, 23 psid, only for EJ engines (thread location of bypass valve)

57830 : 3.29x3,00, 28 psid, for FB engines,

57055 : 2.57x3.40 , 27psid, for FB engines.

 

 

4) Purolator Pure One (99.9% at 40u) and Purolator Synthetic (99% at 25u), 9-11 gpm,thickness can 0.35mm:

PL14615 : 2.69 x 2.93, 16-28 psid

PL14459 and PSL14459 : 3.15x2.95, 12-15 psid

PL14620 (former PL14610) and PSL14610 (PSL14610) 2.69x3.52, 14-18 psid

Pl24458 : 3.15 x 3.94, 12-15 PSID

PL14460 : 3.15x2.95 , 20-25 PSID, without ADBV

 

5) Bosch Distance Plus (99.9% at 40u) and Bosch Long life (both made by Purolator), 9-11 gpm, thickness can 0.35mm:

D3312: 3.36x3.00 , 12-15psid

D3323: 2.69x3.52, 12-15psid

 

 

6) Mobil-1 (11-17 PSID, 99% at 25u), 9-11 gpm, thickness can 0.46mm

M1-104 : 3.14 x3.08

M1-110: 2.67x3.35

 

7) K&N (11-17 psid, 99% at 25u), 9-11 gpm, thickness can 0.46,,

HP1004: 3.16x3.4

This is what happens when you know some parts of the equation, but not everything. Yes, Purolator Pure One is going to filter the smaller particulate sizes better than any other standard replacement filter.

The potential problem is the effect of that cause.

Some Pure One users have reported oil pressure issues with the filter being so restrictive. You would need to hookup some gauges in the right places to confirm your engine is still getting fed the volume it was designed for with an OEM filter such as the Tokyo Roki or Honeywell that restricts less, without being in bypass much of the time. This is not practical for most people, not even for me. So you either take your chances or be safe with the Tokyo Roki.

 

The PureOne is not the Best, it is the Best*

And what is that design flow spec and pressure spec? What would it be on a stage II build with a 16G BNR turbo with a larger oil supply line, taking into account the filter on that new supply line? I have no idea what the original engine design specs are nor what these modifications/upgrades do to the oil needs.

Loaded questions, could write for an hour on each. For the engine oil, see service manual. For turbo, oil supply modifications, that's covered elsewhere. Fortunately with BNR you're keeping a lot of things OEM ish. No easy or simple answers here, so it goes back to a) either keep it the way it was designed to be, or b) change it and either know what you're doing or take your chances. As for the firm numbers for which you're looking, I've seen engine oil and turbo oil flow rates and pressure specs, so it's definitely out there and probably not hard to find. Generally it's simplified down to just pressure, since flow is so hard to measure, and not terribly important anyways (the oil pump usually puts out more than is needed). As for what happens when you add a filter into the mix, it gets less simple.

Took off a Bosch 3300 from previous owner.

Looks just like a Purolator... no surprise here :D

The metallic content in this filter at 2500k miles seems...high! Am I paranoid or is this normal for the inside of a filter after oci... i already tossed the window sticker, maybe i miss read it and i was past my oci by 2.5k? even so... still seems like a lot of metal.

btw... this is the first filter I've ever opened so idk wtf I'm looking for :/

i'd probably drop the dp and check the turbo shaft for excessive play.

I was running the PureONE PL14610 with Rotella 5W-40 since my turbo replacement back in June of 2013. Never had any issues with oil contamination or pressure loss and have a half dozen used oil analysis reports indicating lower than average metal content.

 

With an OCI for the LGT of 3750 miles I have a hard time believing the filter would get clogged up enough for the pressure differential across the filter to send it into bypass mode. I just don't see the lower bypass pressure mattering as much as some folks on here seem to think (unless you're running like 7500-10000 miles OCIs). Perhaps the larger filter medium helps to keep you out of bypass mode during the normal OCI.

 

With that being said, I did change over to the Mazda N3R1-14-302 on my last oil change, however, this was mainly driven by convenience of FredBeans offering a filter and crush washer package deal. I will get another UOA analysis with the new filter (not expecting any issues) and then continue the 2/year UOA from there on out to keep monitoring things.

 

Just my observations based on the data I have from my car. 134k miles.

The one made from natural gas? I was curious about it as well. Marketing BS??

 

Not BS. Platinum and Ultra are both quality oils. Ultra has been majority grp 3+ for a while. Current Platinum is too, now.

All I need now is a hill holder and a center passing light...

I meant the made from natural gas vs the non. I know those are good oils, have used those in many other cars.

That's all fine and dandy, but when the Mazda Tokyo Roki is the same cost with the correct bypass pressure setting why run the risk of pumping unfiltered oil through your engine?

the bypass is mostly the issue when cold start ..

i doubt an oil filter would get blocked enough in 15 000 miles for the bypass to open when hot.

 

i'm still having amazing results running with no bypass

 

and i use 5w20 oil

Now that's thinking out of the boxer!:lol:

fyi all 05 + legacy's have built in code reader
