I have put one on EVERY vehicle I've owned for the last 10 years, like my Jeep, my Hummer, STI, Murano, Tahoe, and my 2010 Camaro SS. I have noticed an instant throttle response increase and 2-3 MPG increase in every vehicle. I still haven't put one in my CR-Z yet. Maybe next month.
FWIW, a company called Spectre Performance makes replacement panel filters IDENTICAL to K&N filters for roughly 1/3 the price. I bout a (big ass) Spectre filter for my wife's 4WD 07 Tahoe for $22.00 at Auto Zone. Not sure if Spectre is/is going to make one for the CR-Z.
