The K&N 57-1557 Air Intake fits some Dodge Ram 2500 Pickup, and Dodge Ram 3500 Pickup models. See vehicle applications link for details.
The K&N 57-1557 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Dodge Ram models. K&N air 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 57-1557 air intake comes with a 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 air intake system accommodates the factory mass air sensor, air temperature sensor and air filter minder. 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. The tools needed are a screwdriver, a ratchet set, pliers 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 57-1557 Air Intake Product Reviews

Monday, November 28, 2016 - Part 57-1557
Easy install and super stiff design. I also dig K&N customer service and pricing. I only buy K&N filters and products.

I am very happy with this product. Does what it says it will do...I love hearing the whine of the turbo and the new found robustness of the exhaust brake (especially in tow/haul mode). I think I have even gained 1-2 mpg. Better throttle response...great improvement over the stock intake I would highly recommend this product - my 6.7 Cummins can breathe again

I installed my intake last week, traveled 500 miles over the weekend a mix of highway and secondary roads. Notice a nice sound, the exhaust break more profound and fuel mileage increased 2+ miles per gallon (which I was very much surprised) I highly recommend this product.

Truck runs smoother than it ever has and starts easier. Increase in fuel miles per gallon maybe by 10 to 20 percent. It pulls my trailer up hills without shifting down. It would be very hard to go back to original equipment. Thank you K&N.

2-3mpg increase, better throttle response and spools up the turbo a lot quicker and it sounds good. I highly recommend it.
