K&N air filter

[Cshat]

Do I need a power commander after fitting a k&N air filter to my bike?
Considering its a 2010 z750 am I correct in saying if the airflow increases due to a hi-flow filter then the computer will increase fuel to compensate for the lean mixture,
If I'm wrong then why do they sell them and advertise no remapping required,

So my bike now has a K&N air filter in it and I must say I'm impressed with the smoothness and throttle response, initial power response is smoother probably not much if any HP gain but I have noticed that in 6th gear at 60kph it pulls away a lot quicker and smoother, rev range is 500rpm lower,
So all in all I'm very happy with my purchase
