The K&N 57-2527 FIPK 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 57-2527 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 past the mass air sensor and 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, crank case vent hose and air temperature sensor (on certain vehicles). 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 the existing factory points and requires commonly available tools to do the job. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

  Hello all @ KN,

I just wanted to take a little time to contact KN and say thank you for such a great product. Since buying the complete air intake system I have seen a huge difference in the performance of my 1999 Ford Ranger 4.0 Prerunner. I will always use the kn product in the future with all of my vehicles now that I have seen how a KN filter helps the performance of my Ranger. I will also highly recommend it to anyone who will be looking for a quality air filter going forward.
