Love this air filter!

When reading the reviews as applicable to late model Mustangs, many said they observed a noticeable increase in horsepower. Additionally, a slight increase in MPG was noted. I installed this filter on my new 2014 Mustang 3.7L V6. I notice smoother acceleration, but a slight decrease in MPG. I was averaging 15.5-16.5 MPG in the city. Now, I am averaging 14.2-15.5 MPG. I don't think the acceleration improvement has lead to a heavier foot, so the airflow may have decreased. Or, as I might expect, the mass airflow sensor has not adjusted to the change in filter media.
