The Filter is Great. I have seen am increase in mileage and pickup power.I messed up one of my orders and it was quickly corrected. Many thanks to customer service.

We have plenty of dust here in Arizona. The air filters I have been buying do not last very long. I thought using your product would be less expensive in the long run. I have not had it long enough to see how it works.

So far so good. The instructions were a little general as to why the added plastic bracket had to be used and could have used some text to describe what was supposed to line up. Once I figured it out, the filter was properly seated. There is a noticeable increase in power from my 4runner's V-6 and mileage has gone up by about 21 miles per tankful (or about 8) I am going on a long road trip and will have a better feel for mileage increase after that. It typically gets 24 MPG freeway. I expect to recoup my cost for the filter in about 6000 miles.
