KN 33-2370, I have KN's in all my vehicles. This one is for a 2012 Camry and I'm sure it will fit the 2011 and perhaps the 2013. In installing these in Toyotas you will see a cotton/carbon mesh filter that is not removable in the top of the airbox. Its a post filter and I believe it has something to do with emissions on the newer Toyotas. You can't remove this filter, nor should you. Buy installing the KN filter you will eliminate the large cotton/paper filter in the bottom of the tray that is removable. This filter is a denso brand filter typically, and is very restrictive. When you get the KN you will notice that its not quite as tall as the OE filter and thats normal so don't be alarmed.
After the installation, your computer will need to re learn itself and it may take as many as three key starts for it to understand that its now getting a bit more air. I'd say within three days you would notice and improvement. Some have noticed improvement immediately. Most drivers with a tuned ear, will also here their engine become a bit more agressive sounding, this to is normal and will not cause damage.
