Used the Afe filter on a 2005 Mazda 3s. The engine delivers the power and the transmission is shifting gears smoother. I can't measure any performance increase but I can feel a smoother delivery of the power as the brand new filter is installed. I don't know how long this condition will last. I hope that it will be for 15-20K as advertised. The price is 4 times more than a factory filter but the benefits are not four fold. I don't think is easy to justify the extra cost. Next filter will be a standrd factory filter for 25% of the price.
