Quality filter
Bought this filter to replace the UNI fliter I purchased 10 yrs ago. It is a quality product. The only issue I had with the old one is the prefilter got brittle and tore when I went to clean it the last time. The actual filter was still good.

Great airflow and Recyclable with a quick cleaning
Stock paper filters used on Polaris trap more dirt but cannot be cleaned without damaging the filter. I purchased 3 UNI filters so I have a clean spare always available. When cleaned and oiled properly they have good dirt trapping qualities and airflow. I believe they are superior to the K&N version. K&N is my 2nd choice

Better quality than dealer
We have not installed. The web site should have recommended the oil and filter cleaner.
