        Great Filter

        Way better than the stock filter. HP increase is likely negligible but can feel a better throttle response. Less than 5 minutes to install.

        Easy to install just pop in and your done. Gave the car a little more turbo sound but not much at all. Throttle response is a bit better.

        Airaid Filter

        Airaid filter is good quality and easy to install. It also comes with a peel back decal to stick on the filter box to indicate not to throw away the filter, it's re-usable.

        5 2016 EcoBoost - PhilipG Installation Time: Less than 1 Hour

        Noticeable (but subtle) improvement

        Had a very dirty filter that I had left on a bit beyond the recommended service interval and swapped it out for this. Difference was immediate and noticeable. I am not going to claim anything crazy but to give people an idea, I would compare it to the difference when you have a full canister in your vacuum vs an empty/clean one. It fit great but did have an oily residue on the rubber gasket part which I wasn't expecting from a dry filter. I rated it only 2 stars for performance gain since it realistically is more of a maintenance item. I do like how it is washable and therefore should last the life of the car.

        Don't expect much gains from this; however, if you don't want to tune your car, this is a better investment than an optional tune CAI with dry air filter.

        Great Filter!

        Bought this for my 2015 Mustang GT. WORKS well, fits perfect. I do notice a slight increase in acceleration. Plus it filters out more than my factory filter. And it's reusable to! It's a No Brainer! Love the fact that it's a dry filter because an oil filter will damage my mass air flow sensor. I had that happen with my BMW.
