air filter

Idk who makes Twin-Air filters, but I will run a UNI filter on just about anything, including my Stihl chain saw if they ever decide to make one that fits. They work very well when oiled properly.
 
i've ran both, uni's now, but had a twin air on my 96 for about 6 years and liked it,
if my old ass memory serves me right....the twin air had tighter foam, so may trap more dirt than the uni ?????
 
I've always ran a UNI on my wheelers. Great protection and performance! Twin Air is very good also. I would just stick with the Twin Air and save your $$$. I always use Husqvarna Bar and Chain chainsaw oil to oil my filters. Works wonders.
 
I have used the cheap Chinese types in the past but do not recommend them as they are prone to the foam breaking down after a few washes.

Any good brand filter is only as good as the regular maintenance it gets, provided it is washed and oiled properly it will clean air.

For peace of mind though I go with the UNI
