I'm happy to have an air filter that doesn't have to be thrown away every time I change my oil.  I haven't noticed that I get better gas mileage but I do think it has increased the power slightly.  Either way the environmental aspect of having a K&N air filter is my favorite part.  It feels right :)

Great product! Increase in horsepower and fuel efficiency. I now have it in both of my vehicles.

Good service in shipping the order and the replacement filter fit perfectly. It was just as easy as replacing the OEM filter and the best part is you can clean it as often as you want and reuse the filter. A few dollars for cleaning supplies and filter oil and you're ready to go again.
