The K&N 57-2525-2 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 57-2525-2 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 tube accommodates the factory mass air sensors, air temperature sensor, idle air control and PCV lines. 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 mounting points and requires commonly available tools. 

  • Guaranteed to increase horsepower
  • Designed to improve throttle response and engine sound
  • Lasts up to 100,000 miles before service is required (depending on driving conditions)
  • Replaces entire factory air intake system
  • Free-flowing high density polyethylene tube
  • Easy to install, usually in 90 minutes or less
  • Washable and reusable lifetime air filter
  • K&N Million Mile Limited Warranty
