I purchased this air filter to replace the foamy OEM on my 08 Scion TC, I figured I had already spent more money on the stock ones. Plus I didn't want to spend a lot on a cold air intake since I don't autocross my car, its just my daily driver. I have this product in my car for about 2 weeks now and I love it, I can really feel the difference on midrange RPM, a bit more responsive. If your looking into something like this without having to replace to whole assembly for an cold air intake I definitely recommend this product.
This product delivers what it says it does plus I don't have to buy filters all the time just clean it and pop it back in, it fits just like the OEM.
