Review on K&N Engine Air Filter: High Performance, Premium, Washable Replacement Filter for 2010-2019 Mazda L4 2.0/2.3/2.5L (CX-5, 3, 6, Atenza, Biante, Premacy, Axela) - Model 33-2480 by Brent Henderson

The filter may seem expensive at first but I have used it on other vehicles and it has a million mile guarantee. My advice is to clean/charge every 50,000 miles (I do this every 25,000) and DO NOT buy a replacement paper filter after the second time, you'll save for the rest of the car's life. And they help you improve your fuel economy by consistently using cleaner air instead of a paper filter that clogs over time. My family is in Texas. We drive a lot of kilometers and if we don't have an accident we drive 250,000 before we buy a new car. K&N filters, Mobil 1 synthetic oil, properly inflated tires and unleaded gasoline will result in fuel and maintenance savings over time. Consider it a good investment for one of your most important purchases and assets in your life.
