Description
UNI Filter NU-8504ST Air Filter Fits Polaris ATVUNI air filters. The principal of how foam air filters work is simple: "Open Cell" polyurethane foam is wetted with specially developed filter oil. The "sticky" filter oil is suspended in the path of the dirty air on the strands of the web like cell structure of the foam. This makes it impossible for the dirt to pass through the strands.

Reliable product
I would buy again. Quality construction. I searched every where looking for right size for my 2006 Volvo. No auto parts store in town carried the right size. Only big cities in Arizona have Volvo dealers. The closest was Vegas and Lake Havasu City. Thanks to Amazon saved me a long drive.
