I love this air filter, the way it makes my 2014 Ford Focus ST sound and perform is amazing. Can't thank my amazing girlfriend enough for getting me this, this past Father's Day. Awesome product.

This is my third vehicle only using k&n filters. I am getting an easy 1.5 extra mpg on average after 1500 miles driven since installation. I will never own another vehicle without buying a K&N filter. The extra pep was noticed right away in the pedal. Better mpg, better performance. It only makes since to use K&N filters.

I had a very frustrating experience with our local [brand] dealer. I had requested a new air filter at 30K miles they said they blow it out so you don't need a new one. At 41K miles I asked for a new air filter because my mileage had dropped nearly 3 mpg. I was patted on the head and told not to worry about it. When I came home, I popped the hood and saw that the air filter cover was still dusty and knew that nobody had even pulled the cover. I took the cover off and found lots of bird feathers from a bird I hit up on the Delta in early February, Harlequin butterfly wings from April and dust bunnies big enough to easily lift off by hand. I should have taken a picture, but instead, I pulled the air filter, blew it out with my compressor and reinstalled it. Then I did what I should have done when I first bought the car, I came in and ordered a K & N air filter it arrived in two days and I installed it immediately. I could hear the big difference the car could breath again! I had had a K & N air filter in my old '93 Honda, so I was well aware of the improved performance. My mileage is back up to where it ought to be, and having lost confidence in the dealership, I take my car to another shop! Thank you for your great products!
