"took a while to install, directions were REALLY generic and unspecific. took me and my two brothers. I did it and they stood by to offer their two cents and make sure I didn't screw anything up. Took at LEAST an hour and a half and there were times it didn't seem right, but it works out in the end.
my buddy and I took my mounty out later that night to the country to open it up some. WOW! sounds VERY aggressive (doesn't sound like it's dying when you get up past 4000 rpm's and sounds absolutely jaw-dropping when you gun it), shifted MUCH smoother, throttle response is much more reliable (the extra juice of the v8 doesn't kick in unexpectedly anymore for seemingly no reason when you don't want it to, you give what you get from the throttle), and it loosened up a couple hundred rpm's. it's cold right now so I haven't really checked fuel economy. my cars fuel economy sucks in the cold either way. we had some warm days and it seemed to be getting about 280 miles to the tank instead of 260, but thats a fairly loose estimation." —Herb P from Saint Charles, IL bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 1997 Mercury Mountaineer, 5.0L V8.
