One of the easiest and most cost effective ways to get more power from your Mustang 5.0 is to replace the restrictive factory air filter and replace it with a high flow air filter. K&N is a pioneer in the Air Filter Game and they have made this air filter specifically for your 5.0 Mustang.
Being a direct drop in replacement, installation is incredibly easy, so it’s as simple as dropping it in and gaining power. They also want to make sure this filter will be in the car for a lifetime so they make cleaning it as simple as possible as well, along with their million mile warranty, this may be the last air filter you will ever need to buy.
