"This unit was installed on a 2003 Ford Crown Vic Police Interceptor.I've only had this unit installed for a couple of weeks. It definately sounds better than the stock air box.I will have to take their word for the 13 additional H.P. as it not something I can feel by the seat. My only complaint is that for this much money, they could have a decent installation guide. You get pictures that don't show what you need to see. Being an engineer I was able to put the puzzle together. A novice may want to enlist the service of an engineer or an experienced service tech. I'm hoping for a measurable inclease in fuel mileage. Even 1 mpg would be good on a car that averages less than 20 mpg...era" —Edward A from Germantown, TN bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2003 Ford Crown Victoria.
