The K&N 57-1503-1 Air Intake fits some Dodge Ram 1500 Pickup models. See vehicle applications link for details.
The K&N 57-1503-1 FIPK air intake system replaces the restrictive factory air filter and air box in some Dodge Ram 1500 Pickup models. K&N intakes are designed to dramatically reduce intake restriction and improve 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 57-1503-1 air intake comes with a logo embossed, chrome lidded K&N high-flow air filter that installs right onto the engine’s throttle body to deliver a guaranteed power gain. The oversized round 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 requiring commonly available tools to do the job. 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 57-1503-1 Air Intake Product Reviews

Saturday, November 5, 2016 - Part 57-1503-1
The filter went on pretty easily. The only problem that I had is that not even one washer would fit on the Z bar threads. I had to use just the nut. You should either deepen the depression in the lid or put more threads on the Z bar. I backed it up as high as I could get it but still couldn't put a washer on. It would be nice if you included a flat wrench that fits the nut. It is a very close fit with little room to work.
