    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!

    Great filter, easy to fit and remove from my Honda Deauville 700. I buy 2 at a time to save the postage and cost of going to a shop. 2 filters last me the year as I clock up 16,000 miles a year. Also fitted the air filter which is doing a great job at 30,000 miles to date.

    I was very pleased after installing my K&N filter on my 2014 Honda Accord Hybrid. It added a noticeable amount of power and it helped get rid of the engine lag. Also helped a bit with gas mileage. Great performance.
