450r Air Filter

[thump4863]

I just ordered a K&N for my 450r and I recieved one for a 400ex. Does anyone know if they are the same? I looked it up in Rocky Mountain and the only difference in the model number is an A after it for the 450r. I looked at the z-400 and the kfx400 and they had the same but the kfx had an A after it. SO does anyone know if the filters are the same on the two?

I PUT A UNI FILTER FROM A 400EX IN MY 450R AND IT FITS PERFECT. DEFINITLE PICKED UP MORE AIRFLOW. THE K&N FROM THE 400EX SHOULD WORK.
