Was wondering how much increase in performance does a K & N filter give the grizzly and what are the costs and best place to get one, thanks for the answers!

 

I have been wondering the same thing?

if you put just the filter in youll notice an improvement, if you put a jet kit in with the filter
youll like the results ,both the jet kit and the filter will only set you back around 140.00 bucks.
as horse power goes,this is cheap for the diffrence youll feal in your griz.
ive done this with an air box mod and went to a 1 1/2 muffler outlett.
every thing ive done to mine has worked well for the bottom end , hasnt seemed to gain any thing on top
All i now is it runs great and will stand straight up on bare road.
