      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.
