Uni vs OEM air filters

Now I know there isnt really a big diff but do the uni filters require oil? and are they worth it in the long run/value.

So even tho they are cheaper are they worth it?

I will be getting either or for both bikes listed in my sig.
 
I really like my uni. Yes you have to oil it. They offer superior filtration to stock and definitely more than K&Ns. They dont increase airflow as much as a K&N but I dont mind.
 
I disagree with the filtration vs K&N, but thats like saying my oil is better than your oil. Its subjective for the most part. And, despite popular belief, ALL filters require oiling at some point. That is part of what controls airflow as well. Just dont OVER OIL, as that will cause as many problems as no oil at all. It simply needs to be barely damp with oil.

Uni is better than OEM, but IMO, NOT better than K&N. Again, however, this is subjective. Uni will likely outlast your stock filter, and filters MUCH better than stock.
 
Uni filters better than K&N. K&N have better air flow for go fast junkies.
I owned a Uni and I liked it. Clean it, oil it and go. As Josh states don't overoil it. You will run rich and foul plugs.
 
The OE filter on a GS550 is a piece of foam, same as a UNI. Some of the UNI filters I've seen have dual density foam - coarse on the outside and fine on the inside, not sure about the UNI GS550 filter though. The OE Suzuki filter is fine-pore so it will scrub the air better than a course-pore foam filter. I'd get OE filter unless Uni is cheaper.

Regarding K&N and Uni in terms of filtering, they are both quite poor. These filters tend to be low restriction and because of that, they don't filter the air that well. Read the linked test below for more information. After reading these tests I make it a point to use a lot of oil on my K&N to help mitigate their poor filtering.
