Great product . I wouldn't use any other air filter on my sports bike and they are rechargeable which is very convinet . My experience was sub-par due to labeling error which sent me the wrong model ( 1000 gsxr when I ordered for 750). I was very impressed by the customer support which was very helpful and got my problem resolved quickly . I was assured that my replacement K&N will be shipped to me as fast as possible. Great costumer service
