So, during my many tasks on the truck these past weeks I took the K&N out for a cleaning. I've owned the truck for a year now and haven't serviced it. I have taken it out to inspect for cleanliness.

While cleaning the filter I noticed it wasn't very well oiled and while doing other tasks I noticed dust on the inside of the intake tube on the engine side. I believe the filter was sealing against the MAF body.

Wish I had could've got a pic. Has anyone seen this with a K&N filter?

 

If you can go back to stock. Less dust and less oil on the MAF.
Or see if you can make a 6.0L diesel filter system work.

But yes the K&N is known for dusting and oiling the turbo and MAF.

Get rid of that junk and get a paper filter. K&N is good at marketing and suck a lot of people into their gimmick

 

yep agree k and n will ruin your engine, alot of dust will get in with all the air they flow, and the red oil they sell, its just tranny fluid, and the cleaner...soapy water. so if you insist on still using it.

 

Does anyone know if the air raid filter/intake is any better?

 

Its oiled, stay away from it. There is little to no gain in HP or TQ with those systems.

 

Go with the AIS factory intake, it seals much better than the junk k&n. If you look close at the sealing portion of the filter it's less than half of that paper filter.

 

Thanks guys. Although the air box is stamped with "Banks" and has a K&N filter in it according to the autozone site the OEM filter looks close in the mounting dimensions to replace the K&N one.

I looked at the AIS one and it sure looks nice. Will that work with the V10? I suppose I could make it fit..

 

Mine did that too, it came with the banks powerpack kit installed on my Excursion V10. I removed the KN filter and went back to stock. No more issues with dusting.

Yeah, I'm gonna go with the stock one. Rather have a loss of performance, if there's any, than a dusted motor.

I was looking at this and I think the PO forgot some parts.

All I saw on the truck is the filter housing and none of the other tubing.

 

K&N = waste of $$$..

just get a quality OEM paper and call it a day.

 

Uh...

I'm a professional mechanic and I can tell where the dust is coming from. You're full of BS K&N.

Taken from their site:

 

That Dust Ingestion .....snip is K&N
doing CYA. If they want me to pull and engine down they can damm well
pay for it. It is interesting to note that the problems start AFTER there filter
is installed and go away after it's removed. I can say this because I had one
of there filters on my Explorer at one time and had to clean the MAF and IAT
all the time.

There is a member in the Excursion forum that has the V10 intake up for grabs. You just pay the shipping. I would PM him to see if he still has it available. Below is the link. It's post #161.

The dusting issue with oiled gauze filters is an old one. All filters pass some particles. If you have a 15 micron filter, particles smaller than 15 microns will pass. I first witnessed the dusting on an '02/7.3 that I used to have. After consulting with several of my techno-buddies we couldn't decide if this was happening because the K&N was actually passing more dirt than the stock filter, or if it was because the inside of the tube was oily and catching the particles allowing them to be seen. When I called K&N, the representative was as cagy with his answers as their media advertising is in print. They talk all about flow, but the issue of filtration quality seems to be an unwanted nuisance. In fact, when I mentioned the possibility of "witnessing" due to the oily tube, he grabbed that ball and ran with it. He'd apparently not heard that one before and liked it a lot. Based on this, I tossed my K&N in the trash and went back to stock. I still have to wonder what the best filter media is though. I've owned Honda dirt bikes and ATV's nearly all my life that use an oiled FOAM filter and never dusted an engine or come anywhere close, and these are machines that are routinely ridden in very dusty conditions. I wish I knew what the right answer was because it seems logical that the oiled filter would be more effective at stopping dirt because not only is it using a physical barrier, but also has the added benefit of the oil to grab and stick to the particles that otherwise would pass. More than anything it was the company's (K&N) inability to give me a firm and confident answer that scared me away. They absolutely would not talk micron numbers. Someday when I'm rich and idle I'll buy all the necessary equipment and give us all the definitive answers!! -- As mentioned above, if you stay with an oiled filter you WILL have to clean the various intake tract sensors on a somewhat regular schedule.
