These are not K&N filters. I don't have any experience with the ones you are showing here but I do know the K&N's are pricey as compared to some of the knock offs out there. Mine were $160 per set of 4 from Dennis Kirk and that was around 5 years ago. Also......you may find the jets they supply won't be what you need. It depends on other things like altitude, compression, big bore, etc. You will have to experiment to find the parts and adjustments to get full performance outa your bike.
