The K&N 57-1556 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Dodge Nitro 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 57-1556 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 air temperature sensor and crank case vent hose. 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. The tools needed are a screwdriver, ratchet set and a 10 millimeter wrench. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Customer Feedback

Ordered this for Christmas and it arrived very fast and was super easy to install and I can already feel the diffrence in my Dodge Nitro. Thanks K&N

Put @ K&N 33-2363 air filter in my 2008 Dodge Nitro R/T with @ 4.0l V6. Factory mileage was listed @ 11 litres @ 100/klm's. After installing the filter, I was down to 8.6 liters per 100/klm's @ a cruising speed of 110 klm's on the highway! Hope my new filter installed in my 2010 Dodge Ram 1500 5.7 litre Hemi will give me the same results if not better. Thanks K&N

All of our vehicles have a K&N filter installed.. The last purchase was for a 2016 Dodge Charger Scat Pack These air filters really work, easy to clean, and highly recommend.
