Let me know how well it fits in our cans.........

Thanks

I will. I'll post some pics too. I looked through my other TwinAir filter and saw same thing so I guess they are all that way. No filter should have any direct paths through the media..(in my opinion)..and I can't see any pin point light showing through the sheet of red/yellow Uni material so..Uni has my vote. I've trusted TwinAir for most of my off-roading life and am now so disappointed in them. They did flow better in tests..just like K&N, but I see the reason is both have lots of direct paths through their material.

Crap, i just installed my twin air yesterday.. for the weekend ride.. and have the uni as a spare. Now i have to pull the twin and install the uni..  good info guys

Yeah I now won't run the twinair at all. Might keep one as a spare though for the top but..it will never be the primary filter again.

OK, here a little vid on the transfer.

Damn straight. The light pinpricks are even more jaw dropping to the eye than the digital pics and vids can show, as the dots of light shining through the Twin Air are smaller than the screen's pixel size and the pics are more of a mush of generalized colour. To the naked eye it's like looking at the stars at night.

Yeah the camera only catches a few of them. I'm so POed at TwinAir right now... I don't use K&N for that same reason...full of open pin holes.

I have about 60 dollars including the  foum filter . I used 2 inch pvc pipe Flange 2 in 90  and  2 inch vacuum cleaner hose the kit had all the fitting that fit the filter and pipe . On the 18 the air intake is inside the cab inlet hoe is less then 2 inches . The flange had hoes I drilled  through the stock snorkel.

Ok so I shortened them up another 3+ inches by taking the upper extensions completely off. Figured I was getting dust anyway might as well see how it looks with them shorter. Like it better but we'll see how it workes out. I have all the other parts to put it back to any height I had before so..we'll see.

NMKawierider,

Have you now thought to maybe turn them forward.....
Maybe catch the clean air coming under the roof and over the back window.
I don't know if you have a gap up top on your rear window, but it might be an idea...

Looks awesome by the way!!!!!!!

Well...funny you should ask..because when they were taller I did think about either turning them so I got air off the roof surface or porting them into the cab so I did flip them around to see if there was room...and there was then but not sure now. Easy enough to check though. Here's some pics of them turned around I never posted:

Looks good that way as well...

I have seen some others run them in the cab, however I don't want to add more noise around my head.

I am planning on trying to turn mine around to see how they work and if the back window will still block the noise.

Think I'll try it too. Ever sense I lowered then the first time I get twice the dust..even with the prefilters so maybe snuggled so it pulls from the back side between the roof and back windshield would be better...and what the heck..they are on rubber fittings anyway.

[2015 Z Force 800 53/Trail EPS]

Na..There isn't any real gap between the window and the roof and there's only about a finger's gap between it and the snorkel head..and it has to bend out pretty much.

My thoughts are that like a stream water system for a cabin, you don't want your intake facing the source but rather facing away (and big enough to have relatively low intake velocity for the needed volume). That way you don't ram whatever is in the medium, into the intake. Bugs etcetera that would have gone right by reversed intakes might slam into the forward facing ones.

[2015 Z Force 800 53/Trail EPS]

Right. By the same token, if they were up above the roof in the air stream and facing back, the airflow around the heads would create pull or a vacuum on the pipes which would make it harder for the engine and/or CVT to get it's needed air. Fortunately..not only are they tucked-away in a negative pressure area already (along with the dust tornado )...but I don't travel fast enough to be a problem...usually...lol
