Pros and Cons on K&N Air Filter

Post by jmgcavtrpr » Mon Jan 22, 2018 9:34 am

So I've had this new K&N air filter sitting around since I purchased the bike and still haven't installed it. I'm in Alabama and Georgia so heat and humidity prevail throughout most of the year. From you Ural Gurus out there what are the Pros and Cons if I install this filter verses the factory/stock one I have?

IMHO the K & N breathes better than stock. K&N comes pre oiled so don't oil it till its first service due. And just very lightly oiled on inside of filter. Just check your factory filter to see if it's dirty. You can get allot of miles out of that stock filter. If you use the K & N filter get the K & N cleaning kit in aerosol can type. Lightly oil!!!

No friend of K&N filter here. (well the blue one behaves much better then the red one) I stick to foam filter. that permits me to ride during tropical rain storms still.

And just very lightly oiled on inside of filter.
Think of how my dad used to tell the waiter how he liked his steak cooked, "Just walk it through the kitchen on the way to the dining room".

It took me three times to finally get the "amount" of oil on the filter right. I use the K&N aerosol kit too, it's much easier to apply. LITERALLY only one application, of a very light spray.

And remember, the Ural filter breaths from the center OUT; just the opposite of "normal" air filters; apply the oil to the INSIDE of the filter.

Since it is necessary to allow the filter element to dry (after w@$#ing) before applying the oil, and then another wait for the oil to penetrate, why not use both filters; one in the bike, and one on the shelf ready to use.

I use'm and they work just fine. Better or worse than stock, I have no idea? But they work. All oiled filters are a pain. As previously mentioned biggest glitch is over oiling. :( When I clean them I let'em sit in the sun awhile to insure they're dry before oiling. Then ever so lightly oil it, then sit out in the sun again for a few hours, then stuff it in a ziplock bag and put it in the trunk/toolbox etc for when needed on the road. Thats for the older carb airboxes, On the fuelies I just carry a stock Ural spare filter. Haven't tried a K&N on the 014. I rather not deal with an "oiled" filter if I don't have to. I'm an efficiency expect...aka lazy. ;)

Same here, I much prefer oiled foam over a K&N for my 07 Patrol. On my 18 M70 the filter isn't subject to excessive water incursion like with the old style airbox, and paper filters filter better, so I run the OE style filter.

Paper filter passes less dirt into the engine than the K&N. But it's your engine and your choice. K&N will probably keep it running longer than you might want to ride it? So it's probably "good enough".

My '07 Patrol came stock with a K & N. Never a problem or thought after the first cleaning and (over) oiling.
Works great for 10 years going.

I'm new in the Ural community but I've seen the K&N pro/con discussion all over. I've seen people claiming the K&N cleans better, increases gas mileage and solves world hunger and on the other side, folks say it lets more dirt in, causes oil fumes to clog the carb/EFI and lead to sudden death.

I've run K&Ns for many years on other vehicles and feel they do a better job trapping dust here in the desert. Other than that, I mainly like them because they are re-useable. Other than that, I feel they are overall not much better or worse than any other filter but I like them.

No not motor oil! Use dedicated filter oil only. The KN stuff works good. I prefer the stuff made for the UNI filters but either is fine.

Like rivers said, if you go with K&N filters, you should use their cleaning and oil kit.
