"I bought this product having seen proven performance and better gas mileage in my previous vehicle. The car sounds mean when you give it the gas, but acts civilized when you are cruising - just how is should be. I was supposed to get about a boost of 17 bhp with this upgrade. I feel it and so does my wife, which is kinda rare that she notices changes to the car. the rubber breaks free a lot more easily now and off the line there is a noticeable difference. I've gained about 2 - 3 mpg with this upgrade, with brings me to 18 city and 22 hwy being fairly aggressive. If my wife drives it its more like 19, 24." —Chad W from Hermitage, TN bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 1999 Ford Crown Victoria, 4.6L V8.
