The K&N 57 Series FIPK 57-3021-1 air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N air 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 57-3021-1 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. The placement allows air to be directed past the mass air sensor 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 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 mass air sensor requiring only a screwdriver, ratchet set and several wrenches. 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 57-3021-1 Air Intake Product Reviews

Wednesday, November 8, 2017 - Part 57-3021-1
Great product. Fast shipping, came with all instructions and was very easy to install. Added quite a bit of power to my GMC Sierra 1500 and improved the sound. I am very impressed, sometimes I even forget how much more power I have. Absolutely love it, great upgrade for any truck.

My truck breathes so much better now that I got this. It made my exhaust more throaty and I had a little better pedal response.
