dyi air filter

[08rap]

i got the riff raff filter ..............what my question is ..........what kind of mounts are you guys useing so it not floping around on the wheel well????i just dont want to mess up the outer wearer on my filter........thanks in advance ...........it would be cool to see a picture of some of your guys mounts

As far as I know, most aren't mounting it. There isnt a whole lot of room for it to flop around in there! Lol.
Mine (just bought a 6637) is just hanging out and is fine but I dont have any outer cover on it.

Mine is squeezed in pretty tight. No mount.

tight very tight, unless of course your Bo & Luke Duke and jumping every lil bump in the road you will be fine.

[08rap]

lol nice heavyhauler i aint going that far

Put it on cram it in. No need for mounts. It will stay.

I zip tied mine to the back of the battery box and zip tied the air sensor to the filter. It is a tight fit, but I feel better with it tied down and not bouncing around.

By doing this type of install your limiting the air flow of the filter...you should get the mount with a new battery tray to insure it doesn't flop around, gets proper radial clearance and correct position of the filter.

FYI...filter covers and their history:

Total waste of money from a performance perspective. They do everything they are not supposed to do. They lower flow by causing additional restriction, have no surface area for high volume, and are unnecessary if you use the properly rated element for the application.

From a filtration view, they can increase filtration efficiency in applications where the filter used has very poor filtration efficiency (ie: reusable/cleanable elements, K&N, AFE, etc). However, they do it will a substantially smaller surface area that has basically no capacity to speak of. It will also measurably affect your flow rate negatively from the increase of the restriction, because you are, in affect, adding an additional layer of filtration with no surface area.

Think about these numbers:
Surface area of Donaldson I use on the Tymar Intake: 4,000 sq in
Surface area of a K&N conical style: 975 sq in
Surface area of a filter cover: 150 sq in

Donaldson has 4 times the surface compared to the K&N, which is significant in its own right, but 270 times the surface area compared to the filter cover, making a filter cover nothing but a hindrance. Filter covers originated from reusable elements inability to filter the air of a dusty environment. Using a proper filter with a proper filtration efficiency and you don't need to worry about it.

Same thing with the guys using them to protect an open element using an improper filter from experiencing water mist. If you use a proper filter for the application that uses a hydrophobic (water resistant) filter media you don't need additional layers adding restriction and lowering flow to gain protection. Again, use a proper filter you don't need to worry about it.

i should of seen that one before well.........i'm sorry to the k and n users i have run dirt bikes and 4 wheelers all my life pretty much ( there junk ) you wont see me running one i have seen way to many motors destroyed from dust ........just for reference ct.........how much dose that tymar filter system run?????? (cost) also i like to run the outerwearer cause the water if any will "bead" up on it instead of soaking into the filter.

PM sent..

water will not soak into a Donaldson.
