When driving down gravel or dirt roads, the tag and the dual wheels on my 2002 Magna kick up massive dust storms. The air intake for the engine is down quite low on the last bay door on the passenger side (a very bad engineering feature) so under these conditions it sucks huge quantities of dust which of course shortens the life of the air filter dramatically. I ordered a custom made Outerwears pre-filter which is pictured. It's an established Company still use them on racing engines and off road gas and diesel engines as well. They will block debris and particles down to .005 in. without interfering with the airflow. The dirt pretty much just falls off as you drive. I have not tried it yet. Has anyone used one of these? Anyway I'll let you know how it goes.

Charles I would be very interested in seeing a picture of the fan deflector you made, but I sometimes have to drive 10 or 15 miles down dry dusty gravel roads and I think it's more than just the fan. I think I have some kind of a sheet metal shield below the fan down there already, though yours may be better. It's the tires in the rear, etcetera. So I am trying this.

I've friends that have used these on their sand rails/ATV's/Motocross Bikes (Or if not these, something similar.) They also use K&N and similar filters, which I won't use on my vehicles. (But, my vehicles are not off roading it, so understand why the use these elements.).
Richard. Is your coach filter the same as my 04 Allure with the ISL, the big canister with the filter tucked inside? And yes, on my coach down in the back left corner about 2-3" off the back of the fuel filter cabinet, passenger side. And direct line of fire from the dust tossed up from the Drive/Tag Passenger side when going down dirt roads(:!
Did you measure to go around the bottom of the canister's intake with the Outwear? Or are you trying to sleeve the filter before sliding it into the canister? (I read you post as the first - around the bottom of the canister's intake.).
I'm intrigued (Well, actually 'allured':)!) by you addition of this Outwear. Only concern I'd have is the combination of moisture being tossed up followed by dust/sand, could combine and cake the outside of the Outwear(?). Especially if in fine clay dust, like say Monument Valley area kind of baby power fine dust, combined with moisture.
Please let us know your real world results, and best to you,

Smitty,
I am posting a picture of my installation. I have a huge filter element that slides in from the bottom under the coach. The intake is on the passenger rear. The outerwear they custom-made for me after I provided them measurements and pictures Velcros to the metal of the intake. It fit perfectly.$60 with the custom fee. Outerwears says clogging is not a problem. They say dust falls off how's your driving since it's a horizontal surface and it's a very slick one. They use these on off-road vehicles such as ATVs in very nasty conditions. I will find out and let you know, but it's going to be some months before I will have an opportunity to do that.

Rich,
Why is there a need for an engine air pre filter on a over the road bus ?

Went to get 6 new tires recently and the tire shop had a gravel lot.....tornados of dust at rear of rig. Same goes for dirt roads in campgrounds, pulling off side of road. Recently changed air filter (lots of dust in element).
I just ordered the same prefilter Rich had made for the same reason (to reduce the amount of excesdive dirt my main engine filter needs to filter).

One very common cause of the dreaded dust clouds is a faulty engine fan controller. If it looses dc power it defaults to high speed. The fan rotating at abnormally high speed while maneuvering
Yahoo Message Number: 114123 (http://groups.yahoo.com/neo/groups/country-coach-owners/conversations/messages/114123)
I also found that my engine temp did not exceed 185degrees with the faulty controller and yes the clouds created behind our bus on a dirt road or parking area was awful. Went to CCI. Eugene and had the controller board changes. $800 plus labor and no guarantee the new one would work any better longer or not! Been 3 years since the change and 20k miles. No problems You could also try the the pilot valve (wax valve). It's been around a while and pretty reliable
Either one will fix your dust cloud problem Good luck on your search

Hey Don, thanks for that.......didn't realize that and now thinking I may be in the default high mode. Looking in to the wax valve conversion (reading a lot about failures in the original controller units). Thanks again!

Allan,
Because this over the road bus drives a fair number of miles off road in remote areas of the North West. If you try it you will see what happens! The rear tires kick up massive amounts of dust and then on my coach the air intake is behind tires not far off the ground so it sucks up this dust like a massive vacuum cleaner which dramatically shortens the life of the air filter.

Don,
I think my fan controller is working since my temps cycle regularly from about 188 to 203. I checked back there and I can hear it's not always at high speed. I'm not talking about driving through parking lots or into a campground: I'll drive 10 or 12 miles down very dry, dusty wash-boarded gravel/dirt roads and sometimes in 80 to 90 degree air temps, so the fan is going to be turning fairly briskly even if the controller is operating. Even pickup trucks kick up clouds of dust where I go. You should see what six 12 R 22.5 can do under these conditions. The paint on my Lexus toad is barely visible there so much dust on it when I do this. If my air intake was where it should be up near the roof this wouldn't be a problem.

Rich,
Although we have different coaches, i have found that the full width mud flap creates a bunch of dust going down "dirt" roads in Nevada. Dust was all over the rear of the mh. I removed the full length mud flap and that helped a lot in keeping the dust down.

I've been trying to see an image or a picture of this device in the files section and cannot find it. Any way that you can help me find an image of this pre-filter device.

Thomas,
You might be right but if I took the mud flap off, the gravel would take the paint off the front of my Lexus toad, and maybe chip or crack the windshield.
Jim Lewis, I have a straight out side exhaust pipe.
Another member, Charles, has sent me some photos of a metal plate he fabricated that extends 5 in beyond the fan housing on the bottom to deal with the fact that the fan blades on our Magnas extend beyond the shroud. He said that it helps enormously with fan dust. I'm pretty sure that the fan contributes to my problem since it's hot out, but I think it's mainly the tires.
