K&N KN-303 Oil Filter Product Reviews

Saturday, May 18, 2019 - Part KN-303
This fit my 2004 Polaris Sportsman 400 perfect and I've noticed a preformance boost. I've used K&N filters for a while now and just got around to checking if they did more than automotive. Thanks

I have run K&N filters on my 2008 Royal Star Tour Deluxe since it was new. The nut made into the filter she'll works great. Great price direct from K&N.
