The K&N 57-1511-2 Air Intake fits some Dodge Ram 1500 Pickup, and Dodge Ram 2500 Pickup models. See vehicle applications link for details.
The K&N 57-1511-2 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Dodge Ram pickups 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 57-1511-2 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 air intake system accommodates the factory crank case vent hose, EVAP assembly and A/C line. 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 57-1511-2 Air Intake Product Reviews

Wednesday, February 15, 2017 - Part 57-1511-2
Gained some great HP. The system is a little hard to get in because the throttle body is so close to the fire wall. Other than that the install was great. Truck even sounds better. My whole family uses K&N products. My youngest son just got his first car and was disappointed he could not put a K&N cold air intake. That's the California law for his car. Thanks for the great products you make, they keep all my vehicles running great.

The kit was easy to install. My gas mileage has improved but I have not ran a full tank through it to actually know how much. Thanks for the help. I should have done this a long time ago. It will definitely pay for itself.

Great product. For a novice mechanic, or everyday Joe, the written instructions were no help. I had to watch the videos to get it installed. Once I figured out where everything had to bolt on to, it went right in and was an easy install. I could feel that the engine had a little more pep than usual and it sounded like a beast. Thank you K&N!

I love k&N products. It does exactly what you'd expect and the quality is amazing. Perfect fit and pretty much idiot proof install. Plus the warranty is seriously amazing. I wish every company would back up their products like this. Definitely worth the money.

Did exactly what I expected it to. Bought one for my Avenger a few years ago and loved it. Just recently bought this one for my Ram 1500 and its still just as great.
