The K&N 57-1533 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Dodge Ram models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Ram’s 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 57-1533 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 air filter placement is near a flow of incoming outside air so cooler air is directed through the aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The oversized oval 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 requiring only a screwdriver, a ratchet set and several wrenches. Existing factory mounting points are used and the air intake tube accommodates the factory air temperature sensor and crank case vent hose. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Product Reviews

  So I'm pretty excited! The power gain is fairly impressive, sounds and feels like we installed a turbo, takes a sec to get to the power zone but once it does it's mean! Between the dual exhaust and my new K&N system she purrs like a beast. Definitely an affordable and quality move for MORE FUN.

  Great product. Truck now bad***!!
David Hines Indiana
  Simple and easy install. Completely changed the sound of my truck.
Tyler Tennessee
  Very loud! But in a good way. Put it on a 2007 Ram 2500 with a Hemi. I have open pipes from Cat back which is already loud. Now more noise comes from the hood and I think the cab shakes a little at high RPM's. Noticeable power but just a little. Gas mileage? It's worse! That's because I'm always on it. It's how a truck should sound.

  I am satisfied and impressed with the increase in performance.
T. Lopez Arizona
  I installed the K&N cold air intake system on my 2008 Dodge Ram 1500 5.7 hemi. My main goal was to improve my MPG. I must admit I was a bit skeptical of some of the reviews I read about the claims of improved MPG. I took two 500 mile trips with identical conditions recorded the MPG before and after the installation. I got a 10.4% increase in MPG. Not to mention the deep throaty sound that my engine makes now. K&N has made a believer out of me. Highly recommend this product.
