I am looking at buying one of these for my quad are they worth the money?

 

u can just get a twin air dual stage air filter for HALF the price...they r supposed to be better for offroading...k&n r supposed to be better in street bikes and stuff....hope this helped...o and it helped my 300 out

 

I have run K&N's with Outerwears out here in the desert for many years with no problems. Just change them often!!

It will help performance, especially if you combine it with an aftermarket muffler and header. (Especially the header, that stock header is tiny.) You will need to rejet.
