"Installed in Toyota Corolla 2003. Very high quality product. Gread shipping time. Works perfectly, but when I was installing it, it didn't fit perfectly at all so I had to cut the filter end of tubing just a bit. Ohter than that this product is awesome. Good sound and noticable increse in performance, even though not dramatic but it never hurts to gain more power." —Aleksander K from Albuquerque, NM bought an AEM Cold Air Intake System for a 2003 Toyota Corolla.
