"I felt a noticeable increase in throttle response and a slight increase in power, mainly at highway speeds. Also, the sound you get out of it is great! Worth the money." —Daniel S from Pasadena, MD bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Ford Explorer, 4.6L V8.
"You can feel the performance gain immediately. Easy add on to improve power and fuel economy. I can tell a decent amount of mid/top end power. It compliments my throttle body spacer nicely and makes it more effective. It also makes the truck sound deeper and more throaty. The only downside is that the heat shield for the filter isn't big enough on my vehicle. Otherwise it seems like a good improvement to my truck." —Connor M from Omaha, NE bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Ford Explorer.
"This product is and always has been the best NO#ONE. I have used the insert air filters in all my cars from 1998-to present but haven't used the full system until now. I thought I was doing something with the filters but don't get me wrong they work too just the systems are more advanced." —Chris B from Jamaica, NY bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Ford Explorer.
"First off, Auto Anything matched the lower price of a competitor on this product, which its great! It took little over an hour to install and the improved throttle response is very noticeable. It improve mpg's by just over .5 mile. Fyi, I have the 4.6 engine." —Matt H from Goddard, KS bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Ford Explorer.
"Easy to install, easy to follow instructions. Adds a nice sound when full throttle, making my V8 sound like one. Stock level of noise when part throttle, making cruising and normal acceleration a nice experience. Says it only adds 10 HP but can feel it in acceleration. Would recommend this piece to anyone looking for a bit more power without too much noise." —Michael W from Durham, NC bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Ford Explorer.
"I had been aware of this technology for a few years. My wife decided to sell our tow vehicle (Ford Expedition) for something smaller with better gas mileage. I found myself having to add a tow package to my Ford Explorer. The K&N FIPK seemed like a necessary accessory to help the truck breath. Not only did I see gains at the pump, but the throttle response has increased. Not to mention the change in tone coming from the exhaust." —Robert G from Huntley, IL bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Ford Explorer, 4.6L V8.
"The item has very good in saving gas. However, the shipment was 2 days late, due to UPS. I have notices better gas milelage" —Martin M from Fredericksburg, VA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 2004 Ford Explorer.
