Which Air Filter

Mine is sock. Are they ok? If so how do you service them? If not, which aftermarket is best? K&N? AFE? Does the stock one require oiling?

I'm a uni kinda guy, others like k&n. yes you have to oil stocker. I use pj-1 cleaner and spray on oil.

i like uni and yes always oil real good or you will get ring and valve damage

how about the afe, its a non oil filter. seems to work good in the dusty conditions I am always in, but am I doing internal motor damage?

uni is made for oil...yours should be fine dry if its made to run that way

thanks

I run afe dry filter on my cummins and they filter really well. I have just always ran uni on my quads and now my rhino

I've been putting transmission fluid on the stocker.

i would run uni oil on it...

just a thought...
don't go crazy with the quantity of oil you use. they can coat inline sensors if you're fuel injected.

Can I hurt it with trans fluid?

i run a k&n with the hard mount adapter

Still running stock. When or if it gets worn, I will go with the UNI. I use PJ1 cleaner and oil. That stuff is amazing. The cleaner works like magic, and the oil sprays on even and is super tacky. No way any dust is getting through that stuff. It's so sticky, I don't think it could get sucked through the intake to get on any sensors.

Is this AFE filter a pleated paper filter? Paper filters are never oiled and they simply have a fine enough pore structure to catch the dust by itself. Oiling them will likely plug them up.

Foam filters such as the stock and UNI filters must be oiled. These are depth filters which catches the dust within the thickness of the porous foam. The foam pores are too coarse to catch and hold the dust without the oil. Fabric filters such as the K&N are also rather coarse in their weave. They must have oil as well.

afe says no oil, guess afe was designed by one of the original engineers from K&N who started his own business...afe

I looked at the AFE website and i'm thinking that those are impressive filters. Have you been happy with the performance (airflow)?

It is not exactly clear to me what filter you might have gotten, ProGuard7 or ProDryS? In the one form, they are taking about the PDS as a pre-filter, not intended to be a primary filter. Yet in another form they are offering 'air filters' for the Rhino in either filter media, with the dry being less expensive. It might behoove you to double check what the situation is. A new fabric filter usually comes to you pre-oiled if it needs to be, so you really don't have to worry about it until it is maintenance time and you clean the filter.

Let us know, as that might be the filter that I choose next go around.
