I was wondering this this morning while out for a long walk. I thought bout trying one on the 2011 Focus. Thoughts, opinions? Please discuss

Anyone still using Bosch Diatance Plus filters?

Sad note for me. It was the last filter I used on my 1989 Accord before I wrecked it in June of 2012. It was just another in a long list of filters I had used in that car. (Fram, Amsoil, Mahle, Bosch, Purolator, Mobil1, Supertech, Honda...)
I ran everything 10K with my chosen flavor of the month full synth oil. I was using Rotella T6 5W-40 after about 300,000 miles to minimize leakage past the well worn valve guides and stem seals.

A lot of Walmart shoppers still use them. I know because so many D+ filter boxes at my WM have other filters in them. Usually Fram EG or Supertech but I also saw a Delco. The box being clear makes it easy to see. They are rated at 99 or 99.9% @ 40 microns on the usual multi pass test.

Link?
Here's the last two I used, one for two ocis. Running last of stash from same lot now same vehicle.

Too expensive compared to WIX for me. Not a bad filter, though.
For the price they ask for them I pass and use Mobil 1 filters.

Better watch out for those M1 center tube louvers that cause "molecular shearing" of the oil and the filter to be in bypass all the time.
j/k but couldn't resist.

The bottom pictures are of a Mobil 1 110 with louvers that aren't open the best. The top 2 are of a Purolator Boss with louvers open in a better way... I do have a Mobil 1 110 on my Altima now that had the louvers open very well. I also have a Carquest Premium oil filter with louvers that are open good too.

You can get K&N HP-1010 at Amazon for less than you would pay for D+ 3323 at Walmart. The K&N has jumbo louvers that are well opened, large media area and isn't restrictive. I personally favor flow over filtration.
As far as other filters with louvers, like other people had mentioned, you have to examine each filter you buy individually to see if they are well opened. It's ridiculous manufacturers don't have this figured out. That alone made me go with the K&N this OCI.
Also, all these synthetic media with metal backing filters, I am not too sure about them. Granted the filtration is great, but amount of resistance all these layers of material result in is questionable. I would really love to see some flow vs pressure drop graphs. But, of course, such information is nowhere to be found.
D+ is a very well constructed filter through. I had personally cut open a number of them.

The full synthetic oil filters should flow better than cellulose or cellulose/synthetic mix. Here's the actual Flow vs Delta-P (PSID) of a PureOne some years back flowing with 5w30 @ 200 deg F. Data was obtained from Purolator lab testing.
Motorking was asked if he could give similar flow data for an Ultra (full synthetic) in the same sized filter, and the data he gave showed the Ultra flowed even a little better than this. Having only a 5 PSI delta-p at 12 GPM with 5w30 at 200 deg F is pretty low resistance IMO.
Almost any filter will have no problem flowing the oil volume that most road vehicles produce, and have a similar curve with maybe some increase in the delta-p, but probably not enough to make any real difference in normal use. Now if you planned on racing the car and it was living near red line for a lot of time, then a few PSID more at full pump output might make a difference to the motor.

The D+ is basically Purolator's M1 competitor (the M1 being Fram-made)
But the M1 is usually cheaper, as well as the newer wire-backed synthetics like Purolator Boss, Fram Ultra, and Wix XP/Napa Platinum that are often on sale.
Simply put, there are better filters at better prices. However, the D+ is still a very good filter for long drains

Interesting pics bbhero, thanks for posting.
As others have pointed out, at this point there are better values than the BD+ in that tier filter. I purchased mine on an AAP code glitch years ago for ~$3.50. Couldn't beat that. That aside, IME they are a quality filter.

When new, is there a graph for when filled to capacity? That would be more like in real life, as when new we expect all is well with flow. The use of two ply media should give the fine layer a break so to speak.

We always rely on U Tube information.

I'm still pretty green with this stuff. Isn't 40 microns pretty large for street use?. Just asking.

That Flow vs PSID data Purolator gave was on a new filter. As the filter loads up that whole curve would be shifted upwards ... by how much would depend on a lot of things. Of course as the curve shifts upwards the delta-p at higher flow rates gets closer to the bypass valve setting.
Full synthetic media oil filters may not show the curve rise as much or fast with debris loading as a cellulose media because the holding capacity is much better on a full synthetic due to its "depth filtering" characteristics.
