I was a bit skeptical when reading the reviews on this air filter and about the increase in gas mileage that people claimed. I have been through two tanks of gas since installing the filter and have found my mpg is approx. 3-4 mpg higher. I find that more than acceptable and combining that with the fact that this is the last air filter I will have to purchase for the car makes it well worth the cost.
