The K&N 57-2529-1 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 57-2529-1 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 the mass air sensor and an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory vent hoses. 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. 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 57-2529-1 Air Intake Product Reviews

Saturday, March 11, 2017 - Part 57-2529-1
Works great on my 2003 Ford Ranger Edge Plus. Previous owner put a K&N filter in the original air box. I bought the truck at a dealer and found that while accelerating fast to get on the highway the truck still felt like it was being held back a bit. After a bit of work fighting to get the air box out I put in the cold air intake. When I accelerated quickly to get into traffic on the freeway the truck accelerated much quicker. When I put the gas pedal to the floor, the truck doesn't hesitate or think about it, but accelerates with authority like a race car. Even with all that torque from the motor, the transmission shifts right along so buttery smooth. Having the extra HP is great because I have a heavy winch bumper with winch and brush guard on the front, custom built tube bumper with tiregate on the back, fiberglass ARE mx canopy, 31 10 ply tires and heavy shocks for all the extra weight.

Definitely noticed a difference in gas mileage and acceleration. I would recommend this product.

Great product. Nothing is better than a K&N. I can feel the power increase.
