 I was skeptical upon initially hearing about this product from a friend of mine. I knew of K&N air filters before and knew that they were supposed to drastically improve horsepower and fuel efficiency. However the $50 price tag was rather daunting. After deciding to man-up and purchase a K&N air filter for my 2004 Ford Mustang 3.9L V6, I IMMEDIATELY noticed a massive improvement in horsepower. Over the last few weeks my wife and I have also discovered we can now fill up about every 7 days, as opposed to the previous 5. Needless to say, our K&N air filter has already paid for itself in the month we've had it. Thanks K&N for making such an outstanding product.

 My Mustang, Jeep, and Canam Spyder Trike all have K&N air filters. The K&N upgrade has given all of my rides better performance, better gas mileage, and keep my throttles bodies clean. The K&N air filters pays for them self.
