Filter was an exact fit for my Polaris Sportsman 500 H.O. Ordering was easy and shipping was fast. I definitely love K&N filters and have used them on many of my trucks in the past.

Purchased a K&N air filter for my '99 Chevy pickup nearly 5 years ago. Since that time I've been extremely pleased with it so I ordered one for my Polaris 4 wheeler. I don't really see ever having to replace either one. The extra that you initially have to pay for the filter is a lot cheaper than purchasing any other kind that you will certainly have to replace in the future.
