The K&N 57 Series FIPK 57-2556 air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. 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 57-2556 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 oversized air filter can be used for up to 100,000 miles beforeservicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using commonly available tools. K&N 57 Series FIPK’s are street legal in all 50 US states and come with K&N’s Million Mile Limited Warranty.
– K&N’s easy to install air intake systems replace the restrictive factory air filter and air intake housing allowing for virtually unrestricted air flow.

– This power gaining air intake comes with K&N’s famous million mile limited warranty.

    Best money ever i ever spent on my 2007 f150. Seems like it dosent work as hard to pull the 35″ tires I have on it after I had the CAI installed. The mileage may be slightly better because I don’t have to get on it as hard.
