I am the third owner of a 2000 Polaris Trail Boss 325. I have no paperwork on it at all, got it at an estate sale. My question is Model #. The Polaris repair manual it shows three models:

AA00AA32AA
AA00AA32AB
AA00AA32CA

I know it has something to do with emissions. On the right side it says "This vehicle conforms to California regulations...."

I need to know what model I have, as certain parts numbers are different. I called a few dealers and they were both a little on the rude side. Any help would be greatly appreciated!!

Also, any aftermarket oil filters out there other than K&N???
