Is that PN 0000 120 1655? I might be able to get someone to return a favor
How many do you want? It looks in the IPL like you don't use the filter cover with this filter setup.

That sounds like the right part number but sadly I don't need them now. It's winter time...
I don't have my saw in front of me to decide if it would be enough material but what about using the media off of the second filter that came with the 681?

The Stihl Extreme Filter setup are for the 880's only as far as I'm aware (not the 660's etc?). The filter setup itself consists of a main filter and foam, non oiled pre filter. They work very well but you can't use the filter cover anymore. They would not be easy to fit to a 681, thats for sure - they are big! The Dolmar HD kit would be far easier to fit. I've seen the Stihl setup pass the dead Redgum test on 880's in really harsh conditions with flying colours...
Photo below is of Laurie's setup (rooshooter) on his GB mill...
The 440, 460, 660, and 880 all use the same filter.

Yup for over a year now, Matt gave me the idea.
I spray the inside of the filter to try and keep it from clogging up as fast. I also apply a thin coat to all of the sealing surfaces, it works really well.
I wanted more air inlet area, especially if I was going to put some type of screen to catch the larger particles. Here's what I came up with.
Here the new slots are laid out. The darkened in area will be removed.
I drilled both ends of each slot. I then used a small cutoff wheel in my Dremel and melted my way into oblivian! I followed that up with a couple files, and finally hit it with a lighter.
I also wanted to add another row of holes here. All air comes in the top slots and has to pass through these holes as well. The rest of the carb box is basically sealed.

Now it was time to sacrifice a new Outerwears I had laying around from an abandoned project.
I cut it into pieces and glued it in with super glue. I had to take care not to get the glue over the holes. I had to glue some intermediate areas, as well as the perimeter, to keep the fabric flush and help keep chips from getting between the fabric and plastic.
The end result looks nearly factory. It will keep all those larger particles out of the filter box, and allow more air to flow at the same time. Not only will this mod help keep the filter clean, but the carb and everything in the carb box.

That looks really really good,
I've been planing on doing something like that to my 7900's for a long time now, I'm a lazy sob. Anyway all I really need to do is cut the slots in the plastic, the screen is already in place. In the end I'll end up getting the HD filter kit.
Here are some pics of my 7900's filter after running about 5 tanks of fuel through her. As you can see nothing got passed the filter.
The screen does a good job of filtering out the larger chunks of wood.

This was all nice and clean and has only seen about 1 tank of fuel since then. .....
Look how dirty the carb is. The entire carb box seems to be taking in too much debris.

That looks really bad! :jawdrop::jawdrop:
Is there room enough to cut a section out of a dirt bike's foam filter & place on the inside of the cover? Most dirt bikes have two layers with different porosity..take that inner layer fine porosity foam from a dirt bike filter & run it dry. Would there be too much restriction? Would there be room? If you could seal the air box and only draw thru the part dirt bike air filter, you could eliminate the internal filter all together.

Running standard OEM filters on the 371, 385 and 395.
The 371 does not pass anything regardless of what I'm cutting.
The 371BB is consuming a greater volume of air over a stock 371/372, possibly 20-30% more.
The 385 and the 395 pass fines. Go figure?
I was thinking along the lines of Bob's theory, but the 371 sucks more than std.
Differences in the filter media? Can't pick it by the naked eye.
What I'm going to try when I get the chance is a sleeve of mesh with oiled filter foam over the OEM filter keeping the OEM filter oil free if possible.

nice work, mr. snelling.
the only thing i'd do diferently is use a stainless screen under the slats in the top cover rather than your filter fabric. i would worry about the longevity of the fabric on an outter area of a work saw. the fabric on the inner holes would be just fine though.

For everybody's info I was in contact today with a decent Australian Stihl dealer. Have passed this info onto Brad but for those in the US/Europe worried about the filtration on their 460/660/880 Stihls I can get hold of the Stihl Extreme Conditions HD filter kit via this excellent dealer (FYI Stihl Shop Huonville - Tasmania). Our dollar is up pretty high at the moment so doesn't really suit you guys in the US (it suits me from this side getting gear from you!) but I could probably land the kit there with no profit from my end for about the USD$120-130 mark depending on freight and size of the parcel. Pretty pricey but some of you may think it is worth it. RRP in Australia without freight to me is about USD$90-96.
PM me if interested.
P.S. As the cover can't be used they are no good in wet or rainy conditions!

Jacob,J, you said "Yeah all saws ingest a small amount of fine dust and debris over the course of being used and this is usually what kills the main bearings. Debris and vibration."
Well a local logger friend had been running 7900's for a few years and liked the way they cut. However, the other day he said he switched to ported husky372. He said the bearings went out of the 7900.
I thought it odd but your statement along with the poor air filtration kind of brings it all together.
The dealer (D&D Enterprises) told me when I was looking at saws that the Dolmar last a long time but not as long as a Husky 372. Maybe its the AIR.

Nice work Brad! There isn't any way to put a velocity stack and cone filter on the 681. I believe that I have seen one of your stihls with the air filter cover cut out to accommodate a cone filter.
