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.
The K&N 57-2523-2 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford Mustang 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 57-2523-2 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 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 and accommodates the factory mass air sensor. The installation requires commonly available tools to do the job.
  • Designed to improve throttle response and engine sound
  • Lasts up to 100,000 miles before service is required (under normal highway driving conditions)
  • Easy to install, usually in 90 minutes or less
  • Washable and reusable lifetime air filter
  • Replaces entire factory air intake system
