To make a long story short K&N has the best prices and the best customer service. My filter was lost in transit and I had one Next Day Air as a replacement sent to me. You can't ask for more, I wouldn't hesitate to use K&N for my filter needs.

Saw an increase in MPG by 2-4 during the first week. Picture shows 37.1 MPG during a commute during which I normally get 32-34. However, it was only one time miracle and nowadays I am seeing only 1-2 MPG increase overall and I have no clue why. I'm still happy with the product because of the better spool sound from the engine when accelerating (my car is turbo version) gets me nice feeling. Seems not perfect, but great for the price.

Easy installation, better air circulation, better sound and improved gas mileage. Ease of cleaning makes for cheaper maintenance in the long run. Great product.
