I notice a increase in engine power of at least 20 percent. Mileage has not improved, however.

Green Air Filters produce Horsepower and fuel economy! Green Filters are the best since K&N was introduced 35 years ago Green Filters have found a way with modern technology, and refined techniques, these filters actually produce everything i expected and more. I have purchased more then 8 of these filters for all application. I've put them in my parents cars, all of my cars, and given them as stocking stuffers to friends and family. Run a Green Filter, you can't go wrong.
