Well nitrile is not bad. Just silicone is better. The vehicle only goes for 6000 OCI (6000 and then when I get around to it). I mean it's a Crosstrek, not my babied PSD.

Baldwin is old school, not a lot of lines of filters to upsell, or any, in the consumer grade. You get the Baldwin oil filter, simple.
And made in the USA. I am sure many countries can make quality filters besides the USA. But made in China is more likely to be cheaply made.

That is actually a great marketing idea.
No need to come up with some clunky name for a chinesium product. Just be honest and call it "China Brand".
To bad it has horrible efficiency. 45 absolute…..I’m sure it doesn’t have a Subaru bypass spec for those that want it.
Subaru older service part (Blue Painted Fram) had black (nitrile)adbv, where the similar Honda (Blue Painted Fram) had an orange adbv, IIRC. These 7317 size filters are widely used on most all Asian cars-
Nissan, Mitsubishi, Mazda, Subaru, Honda, Infiniti. - but not on most Toyotas.
There are some good factory choices. The Mazda O.E. part has been a darling in the past.
I would prefer a Japan Tokyo Roki. I don't know why manufacturers bean count this important part.
The shorter/wider perfomance spec filter should fit, but I (personally) would not run a 30psid or 17psid bypass.
Great idea! Yeah, something even more Chinese like ChInEa or even 机油滤清器 = Oil Filter. Have fun with it.

They also do rebranded industry filters …
Prior to its purchase by Parker Hannifin in 2016, Clarcor made most of its Baldwin and Hastings filters in Nebraska. I'm not sure if they manufacture overseas now. Baldwin was the premium brand, Hastings was the middle brand and Casite was the value or jobber brand. The Baldwin B1402 filter is a stout filter. I've used many of them in my Honda Ridgeline and other Baldwin filters in my lawn tractor and standby generator. A good source for Baldwin filters used to be www.zoro.com.

My understanding was that Casite was Hastings jobber brand prior to Clarcor buying Hastings and rolling into its manufacturing with Baldwin that they already owned. From that point on, every Hastings labeled filter was a white canned Baldwin for all intents.
I do not think Clarcor purposely marketed Hasting filters as "middle brand" and was more about keeping legacy customers already use to the branding prior to their acquisition of it.
Well I emailed Baldwin and they confirmed it's 45 micron absolute. I wonder why. I assume they could use better filter media if they choose to.
But do they actually need to be more efficient? I have said it before that the chase for “better efficiency” seems to be more for marketing to retail consumer end users to sell higher margin priced filters than actual technical need by the vehicle/engine manufacturers calling for it.
In my observation of Baldwin filter efficiencies, never been known for a high efficiency 'rating.' That said, fwiw my 'speculation' that rating is at least as good the Suby OEMs, maybe a tad better. I base that on what's known about Asian OEM filter efficiencies in general. At this point, just use the purchased Baldwins and don't overthink it.
From someone at Baldwin who answered my email.

The media used in any filter we produce is based off of the media analysis performed on the OE filter during the development or our product. Yes, we have medias that have absolute ratings at smaller particle sizes. However, as you tighten up the media to increase efficiency as smaller particles, you begin to sacrifice contaminant holding capacity.
If you do wish to use a filter with a smaller micron rating, the B7318 is the same size filter with similar features and it is 27 micron absolute. Please see he performance data below.

Please understand that using filters other than what we list for the application may void the warranty on the application of the filter.

There are different car brands using the same size oil filter in quite a few cases. So they pick the best OE filter of the many brands to duplicate? I don’t think that makes sense that happens.
The capacity also can be high or low and not be related to efficiency depending on the media construction and amount.

About the part in bold. That's true, like seen with the Boss and Wix XP ... their efficiency isn't good, but have a decent holding capacity and therefore a good "up to miles" rating - they are often advertised and long OCI filters.
But the part he didn't know or say is that it holds more because it lets a lot more debris through and sheds a lot more debris as it loads up and the dP across the media increases. Debris can also shed off with sudden dP spikes like caused by sudden engine RPM increases, etc. That's one big factor on why it's inefficient. You can get high efficiency filters that hold plenty of debris for most people's OCIs. A high ISO 4548-12 efficiency rating means the filter isn't letting much debris through the media, or letting much already captured debris shed off the media and go into the oiling system.
