Dodson Replaceable Stock Filter
My bad, i coulda swore it said 300 when i read it... even still dodsons "WINNING!" Haha
Gunna try to get my service manager to try and get me some specs on the oem filter... hes super mod friendly and bored so it'll give em something to do

100 microns isn't that impressive, the standard engine oil filter is 30 Microns.
Was it not stated that Dodson filters at 30 microns, which is better than 100 microns? Maybe I am a little slow, but smaller numbers usually mean smaller measurements.
I emailed dodson directly and asked them what the filters micron rating was... which they told me 30 micron
And i echo your statement about 100 microns being unimpressive filtration
Guess the next question to each company is their absolute/nominal filtration rating
" A micron is a unit of measure in the metric system equal to 1 millionth of a meter in length (about 39 millionths of an inch). The average cross-section of a human hair is 40-90 microns. The human eye cannot see anything smaller than 40 microns in size. Two filters may be considered to be 10 micron filters, however, one may remove a greater percentage of 10 micron size particles of contaminant, thus the filters would not be considered equal in performance. For a micron rating to be useful, you must know the filters’ removal efficiency of the specific particle size in question. The term “nominal” micron rating typically means that the filter is capable of removing 50% of a specific size particle, however, some companies’ “nominal” micron ratings may range anywhere from 1 to 98.6% efficient at removing a specific particle size. The term “absolute” micron rating means that the filter is capable of removing at least 98.7% of a specific size particle. This rating is far more accurate."
And to satisfy my curiousity i've sent emails to both dodson and SSP to get further details on all their filters ratings

The SSP "Lifetime Replacement Filter" has 300% MORE filtration material then the Dodson unit and has been spcifically designed to filter MORE of the fluid rather then letting it simply pass through the bypass valve.
The SSP "OEM Replacement Filter" has the exact same micron rating as the oem Mitsu filter.....our's it just 1/2 the cost!
The SSP "TX Race Series In-Line Filter" is 120 micron reusable filter.
Keep in mind there is another internal filter inside the SST with a magnetic strip that also collects allot of debris/wear materials, so it's NOT like you're only running one filter.

A few questions then...
300% more filtration material ? where did you get your figures from ?
Do you have a fluid flow bench ?
Why would you have 120 micron filter as a final filter in a DCT ?
How clean are your filters prior to installation ?
What temperature rating do you place on your filters ?

When introduced to a newer technology such as our stainless steel wire cloth filters, it is natural for people to have questions.
Amount of filtration material: In filter manufacturing circles this is referred to as surface area. The filter style that offers the least amount of surface area is a disc, or flat type. The surface area is basically the area of the circle. The next in line is a cylindrical, or tube type filter media. The surface area is the height times the circumference of the cylinder). An easy way to increase the surface area of a cylinder is to pleat the filter media.
Deeper pleats and more pleats mean more surface area, but this is not always a good thing. For example, if a filter is built with so many pleats that the pleats are resting against each other, the “effective” surface area becomes no better than the cylindrical filter because the filter surface is just the outside edges of the filter media. There are other engineering factors that also come into play as the pleats become closer due to the physics of fluid flow (changes in direction, etc.). The pleats in the SSP filter are designed to allow much more “effective” surface area by utilizing pleats of a certain depth and setting them an ideal distance apart. This provides maximum flow rates as well as providing a media surface that can be cleaned. As our filters achieve maximum flow while providing sufficient filtration, which produces best overall performance. Filter manufacturers often chase tight filtration rates, which often come with the negative byproduct of frequent bypass operation. Once the bypass opens, the fluid will take the path of least resistance and flow right past the filter media and through the bypass.
By measuring the flat (prior to pleating) material used in the SSP filter we know that it is 3 times the length of the material that would be used in a cylindrical element of the same diameter. Said another way, the pleated element used in the SSP filter provides 300% more “effective” surface area than a cylindrical filter. Or you could say the SSP filter can be 2/3 plugged with debris, and still have as much filter surface area available as a new cylindrical filter.
Determining filtration level of the SSP filter: The filtration level of a particular micronic filter cloth is determined by wire diameter, thread count, weave, and other factors. These specifications as they relate to the SSP filter, as well as the bypass design parameters, are proprietary to SSP Performance.
The flow provided by the SSP filter: Flow and pressure testing on a filter with the same size surface area as the SSP filter showed a reduced differential pressure (resistance to flow) from 20psi in a paper filter to less than 1psi for SSP filter.
How “clean” are the SSP filters: All of the SSP filters are manufactured from new, unused materials sourced is the U.S. As with any internal engine or transmission part, the end user is responsible for making sure the part is as clean as they need it to be before installing it.

Kris, to summarize the above, please correct me if I'm wrong:
The SSP lifetime filter, while having a larger micron count, has a much larger surface area resulting in greater filtration overall.
Also, information I've gathered from other threads/other forums is that the matter found flowing through the SST is generally not microscopic (to the 30 micron level) and 100 microns is more than sufficient, and logically, would increase flow through the filter by not having a too fine of mesh.
If I can use a training analogy:
It's like cardio training vs fat burning training. While fat burning training burns a higher amount of fat calories, you still burn less overall calories. While cardio training burns less fat calories slightly, you burn a significantly more overall calories resulting in more fat burned ultimately!
So with the Dodson, you filter out finer particles but the surface area is significantly less and a finer mesh can potentially reduce flow.
Both lower surface area and slower filtration = Dodson less overall filtration capabilities
Larger surface area and more flow while still filtering out all necessary particles = SSP better filtration

I think the real question is, does the SST really need a higher flow rate filter or one that gets smaller particles? Does anyone know what rate the fluid flows through the SST filtration system(or the pressure it tries to push through with)? Having an extra capacity in flow rate is pointless unless the system can take advantage of it or even needs it. Sure it could hold more junk, but if you are changing your fluids at proper intervals, I don't see how that is needed.
In a perfect setup we would have the finest amount of filtration while providing sufficient flow rate. How do we know where the balance is? How about a 200 micron that flows twice as fast as the 100 or a 400 that's double that! I'm exaggerating, but I think you get my point. If we know what level of filtering we need and what flow rate we need, there really won't be any debate on what filter to use.
Unfortunately some people use smoke and mirrors.....
The fact is that the fluid that goes to the secondary filter is restricted by a <3mm orifice. It flows through the filter directly when cold and is directed to the oil cooler when the oil thermostat opens. This also means that the fluid flowing through the oil cooler is only supplied by a <3mm orifice as well.......
Pretty sure that answers the questions about filter capacity, quality and flow.
