I bought a M1-108 filter, and the louvers are barely open on the center tube. This particular filter has the louvers punched so that they alternate - the louvers facing the base plate barely crack through the metal: the opposite louvers might poke out slightly more. I have not cut it open yet: the main outlet hole is too small to allow my dental mirror to reach in. Functionally the louvers are close to be closed. Advice ?

i don't buy oil filters with Louvers for more than 1 reason...

Pics or it didn't happen.
I had pics of the Wix 51358 that happened.
Does the Fram Ultra have louvers ? I forget.

Some do. I can tell you for a fact that the filters for the Cummins 5.9/6.7 do, and also for the Powerstroke 7.3. But they were very big holes.

If I had a PS or Cummins, louvers would be likely, since Hastings and Baldwin would be rather good choices for those engines, and we know what they use.

You have written that a thousand times. Even got off on some turbulence stuff once.
My Fram Ultra's have very few holes - mostly blank tube ... must be turbulent flow there too ?

The problem with that theory is every louvered filter has many times more openings per square inch than and filter with round holes. Some brands have an incredible amount of louvers. Yes you can get flukes in anything.

Same here...
I hate that they are going to this design, I will never run one of these filters.
OP.. I would return it and do not use it use a filter with hole center tube.

Louvers are a much better design and easier to manufacture at the stamping stage.
There I said it. Again.
BTW, I work in the Automotive Metal Stamping and assemblies industry. I think I know enough about how pierced holes and lanced louvers are done.

As a former machinist I can see that. Seems to me we are seeing more, not less of these tubes. So how to trust but verify. I cut up one that looked bad but was actually fine. Can't do that every time - and even if the small mirror works that is odd. Would have been better if they had placed the tube 180 degrees from how it was ...

Absolutely-there's little chance of a "hanging chad" when a louver is punched, unlike a hole. It all comes down to poor quality control-I would be curious to see Fram's response to the OP's issue, I would hope it would be better than the non-existent Puro/Mann & Hummel response.

4WD i have to agree with you on the fewer Holes in the center tube on the Fram ultras i know a number of people that won't use them because of the fewer oil holes in the Ultras.. A lot of the engine guys (rebuilders) Like filters with lots of holes usually the better Chinese filters or the a/c Delco are their choices..I like the ultras.

One by one I hope they will migrate to cartridges on top of motor. I thought my Cruze filter looked tiny - but I put one next to the M1 I cut out ? Same OD but cartridge was about 40% longer ...
Champ is in bankruptcy and it a fairly small staff left to make these. From news in 2015 their jobs are being sent to other countries. The machines need to be adjusted and maintained by employees who are diligent and care about it. I don't know what Purolator's excuse is for their louver problems. I chalk it up to bad QC and supervision on the factory floor.

Has nothing to do with Fram.

I bought the exact same filter with the same problems as you are seeing with yours. My advice is to toss it in the recycle bin and buy a Purolator 14612. The 14612 does not have the same problems as some others with media tearing after usage. Alternatively you can go with a FRAM 6607.
Purolator has louvers, but are designed well, so flow and filtration isn't going to be an issue.

If it's so easy, why can't these filter manufactures put out louvered center tubes with consistent louvers that are opened up a good amount.
We've seen example of the same exact filter brand & model having louver openings all over the place. It's just sloppy manufacturing - should be easy, but apparently not so much.
