when reading a while ago you guys said that the K&N air filter for the 600 grizz would fit on the 660 you just needed to do a little trimming. where would you do this trimming? also how do you oil it? do you have to use the spray on oil? i got an outerwears cover for it. please help me out.

 

I had to trim some of the internal ribing on my Raptor. Quite a bit of it too since it's a lot bigger.
It comes oiled. It should be red looking.

Get a K&N recharger kit.

 

You've gotta trim the top and the bottom of the plastic on the K&N, hold it next to teh stock and you will see how much thicker it is on the end that sits in the air box. I did mine on a sander so it went quick.
