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 Brad Atl

Great fit! What ease! Why are they still making paper filters? This is the fourth K&N product that I have purchased. You can't beat investing in a K&N power filter. I changed the filter in seconds and the factory oil was perfect (don't worry it was oily). Love the ease of cleaning and knowing that they'll be saving me more money over time because they're durable! 3-4 cleanings later and I save money. No noticeable performance benefits, but maybe a little more responsive. I'm resetting my car's mpg so I'm interested to see if I can get something there. I would estimate the typical +1mpg from previous experience.
