This part was an exact match for the air filter housing. The element is about 1/2 the thickness of the stock Toyota part. No problems with the installation.

I've bought several K & N filters, for my Toyota's, and they are a perfect fit, easy to install and gas mileage is up just a bit. The new stickers wirh warnings for service shops that are not familiar wirh K & N was appreciated. Oly

Very easy process. The filter arrived on time as scheduled and installation was a breeze. I haven't really noticed a whole lot of improvement in miles per gallon but I have noticed a change in acceleration and engine idle so in the long run I think this will save wear on the motor and possibly increase miles per gallon down the line I'm not sure yet. The product was as advertised, pre-oiled very simple.
