This is a great reusable air filter. It appears to be made very well and looks on par with a K&N or aFe. I wanted a "non-oiled" filter and this one is it. I have used it in my 02 Subaru Outback Legacy H-6 engine and it has performed very well. Our gas mileage had been around 25 mpg but our last trip with this filter we averaged 28-29 mpg. Very happy with this filter and should last as long as the car does.
