I found out why the TRD air filter doesn't do anything, its make in Kalieforniea USA 
After a year and four months and 25000 mi. I cleaned my TRD filter.
It wasn't very dirty. There were no bugs, leaves, acorns etc. Its is a free flow filter but I don't think it should let BIG things through it though. It might be that the OEM paper filter is white and the TRD is green. It might be that I haven't gone off road this year either
The cleaning kit says if you don't drive much, the filter might need reoiling if it looks like it needs it. How do you tell if it need it???
