The K&N 57-2567 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford F250 and F350 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your 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 57-2567 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose. The oversized cone shaped 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 usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, a ratchet set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Wow I can't believe how good this air filter is. I drive a 2014 Ford Focus Hatch automatic with dual clutch transmission. I bought this air filter based on the recommendation of a friend. I really can't believe what a difference this air filter has made in my vehicle. This air filter has great improved my low end torque and acceleration. It has not made into a sports car but there definitely is a noticeable improvement. Periodically I would get that transmission stutter from the dual clutch transmission, not often but once in a while. With this new air filter I have not experienced that once. This air filter has worked so well I am thinking of investing in the air intake system for $299. There is no reason you shouldn't have on of these filters in your car. A life time part for $60. Instead of paying $20 every 10,000 miles. This really is a no brainer.

The K&N cold air intake kit is great on my 2005 Ford Explorer. I ordered the kit about 2 years ago. I pull a heavy trailer. The explorer is barely big enough to pull it. Installing this kit is a BIG help in letting the engine breathe. It sounds great and makes me feel better too, putting this load on my car. The installation was straight forward and the instructions were excellent. The installation was no problem. Only 2 minor issues. The airflow sensor mounting pad had a casting lap that deformed the mounting surface. I was able to smooth it out with a sharp knife and light sanding. The other issue was that I mounted the filter such that it was riding hard on the bottom of the intake box. This was my fault. I didn't find out until I took the filter off to clean and re-oil it and found a very small worn spot on the filter. When I install this new filter I will make sure that the filter is free from interference all around. Thanks for a great product I'll be using K&N from here on out.

Have installed K&N on my last 4 vehicles: 2010 ford F-150 , 2011 Chrysler 300-C 5.7 Hemi, 2012 Jeep Grand Cherokee 5.7 Hemi, 2013 Dodge Charger SRT-8 6.4 Hemi. And I have been pleased with the performance and sound from all four.
