nope some people say they can feel a difference, but i think it's just psychological one thing that may be worth noting is that, while the engine may breath a little easer and sound throatier, due to the KnN filters being oil soaked to aid their filtration properties, this oil coats the AFM sensor which ultimately causes it to fail and stop your engine from working properly... just food for thought ;) you're better off going for a cotton filer that doesn't take oil

they dont give you any real power...waste of time

Stick with the standard panel filter
