I've always used K&N for all of my cars and quads. I checked my local shop and they checked with K&N and they said they are currently working on a air filter for the 700xx, but no ETA as to when it will be available. I have never used a UNI filter, but my buddy had one for his 450r and said it came loose after a long day of riding was just laying in the box. Kinda makes me hesitate to get a UNI. Should I wait for the K&N?
