When to replace a reusable air filter in a superduty truck?

Yes, I have read that test done many years ago many times. However, as was stated in the original document, they only tested a sectional cut out of each filter and the big difference between stock filters and aftermarket filters are is size.

What that tests also proves is that yes, stock paper filters do have higher ability to capture dirt, higher dirt capacity, and lowest dirt passing through, but that they are also more restrictive per sectional cut out than the aftermarket. This has been known for years which is why it is a give and take on filter efficiency over filter restriction. The question is, how much dirt is allowable and will not have any effect on your engine versus how much will hurt it. If you can increase flow while still being within safe levels of silicon on your UOA then what is the problem?

There is the other thing that the test does not test, which is size of the filter which will make a big difference since most aftermarket intakes are considerably larger than stock ones. As stated in my last post, increasing the size of the filter increases available flow, it increases the filters holding capacity, and helps lower EGTs among other things. Take the second to the last chart where it talks about dust loading. Filters like the AFE Pro-Guard 7 did considerably well when stacked up against the other paper filters when it comes to its ability to capture dirt and how much diest allowed to pass through in a section. It also at higher flow rates per section. However, most Pro-Guard 7 is more than twice as large as a stock filter in many applications increasing its overall dirt holding ability and sectional dirt holding ability since the pressure is more spread out over the whole filter instead of a smaller square.

" I also know that the Powercore filter was developed for the Abraham A1 "

I'm sorry but I can't let this pass. It's Abrams M1A1 Tank (now A2). Named after General Creighton Abrams. Among other accomplishments, he served under General Patton and the tank battalion he commanded broke through to relieve the siege of Bastogne in Dec, 1944. We need to get his name right.

The only data that I have to back this up is what I listen to and read. Most of the forums that I'm on state this, so with the 6.0 being so picky anyway, why would I waste my money on it? I also talked to my mechanic, he has no dog in the fight since I change all my filters and fluids myself, and said unless I was really going to increase the HP, the stock filter was my best bet. Agree with me or not, I don't a have reason to waste the money on something like that.

And how do you know what the people are saying is true? People make assumptions and opinions every day in forums and try to pass them off as facts without any way to back them up. What testing did your mechanic do? What air flow rates did he test and what aftermarket intakes did he test them on? Did he use the ISO 5011 test? If he did, was it with a sectional cutout of the filter or the whole filter. I know filter size alone make a huge difference in EGTs and efficiency for diesels from the testing we done with Fleetguard(a Cummins company) when I was at Cummins. So what dyno charts did he show you that proved they make no power, increase efficiency, or improve EGTs?

Then there is this statement "I don't a have reason to waste the money on something like that". Was that what the OP was asking? No. he was not asking for opinion on whether people think they are good or not, he was asking when to replace a reusable air filter in a superduty truck. Since you do not like aftermarket filter then why did you grace us with your opinion? However, since you did grace us with your opinion I would like to know what data you have to back up your "the stock one is good up to about 500 hp" claim or that it does not make a difference. If it is true and legitimate then I will agree with you, but if it not then I will just chalk it up as an opinion. Afterall, do you really expect me to believe everything said on the internet without data backing it up especially forum posts?

I would love to see the data you have that you are basing this on.

I agree with mudfuel. The Donaldson air filter can support that hp and it's capable of holding a lot of particles. This filters IMO are second to none.

I know about Donaldson Powercore filters very well and even know the Donaldson rep for Texas who is lives in Houston very well. I also know that the Powercore filter was developed for the Abrams M1A1 tank during the first Iraq war due the tanks having to stop every three hours to change air filters because the sand was clogging them. The Powercore filter extended that interval three fold.

However, that is NOT what I was asking. I was asking what kind of solid data that he has that can back up his "the stock one is good up to about 500 hp" claim. Afterall, why say it if you don't have any way to back it up besides what some mechanic, who more than likely does not have data to back up his assumptions either, says?

I don't post opinion here and try to pass it off as fact, which is why I asked what data he had to back up his statement. If he presented it and had legitimate data to back up his statement then I will say okay, but if he doesn't then it is just baseless assumption and opinion.

I love opinions...

the best air filter or any filter.. is 1 minute before it is Full of dirt and start becoming MORE restrictive...


and YES washable filters can become BAD... over pressure of WASHING will bend the fibers and allow STUFF to pass thru.

Never use water force, air pressure or anything to distort fibers... so washing/cleaning .. even applying oil is to be done gently
