The K&N AirCharger 63-2585 air intake system replaces the restrictive factory air filter and air intake housing in some Ford Fusion models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Fusion’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-2585 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that mounts into the lower air box. The placement allows air to be directed through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install requiring only a screwdriver, socket set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

K&N 63-2585 Air Intake Product Reviews

Tuesday, April 5, 2016 - Part 63-2585
Excellent product. Received it in 1 day....FREE shipping. Easy install with easy to follow instructions. Sounds great and immidiate improvement in throttle response. I can't really feel the HP gain but definitely notice the torque gain. Highly recommend. IMPORTANT: You need a 3/4 inch drill bit if your sensor is the push in type. For some reason a Ford Fusion has 2 different types of sensors. I had my stock parts removed and had to get a buddy to run me out and get a drill bit. Other than that, 45 mins to install.

Installation was mostly easy as I had some minor trouble with the air temperature sensor because I didn't have a large enough drill bit to make the hole big enough for the sensor. This product adds some extra sound. I am unaware of the HP gains as I am not equipped to measure. I could not feel the acclaimed 10HP gain and did not record any before or after times to see if there was an improvement. I really like the ability to clean and reuse this air filter for a very long time.
