The K&N 57-1571 is a FIPK-style cold air intake for the 2015-2016 Ram 1500 V6-3.0L DSL (EcoDiesel), built around a roto-molded tube and an oversized oiled cotton filter. In a chassis dyno test the manufacturer ran on a 2015 truck, output rose from 187.89-hp at 3,300rpm to 199.12-hp at 3,300rpm, and torque went from 300.00 lb-ft on the stock air intake to 315.34 lb-ft. That is one test on one truck, so treat the gains as the manufacturer's estimate.
Fitment is where buyers should slow down. The manufacturer lists this kit for 2015-2016 Ram 1500 3.0L V6 EcoDiesel trucks, and its layout uses the truck's original bolt locations and keeps the stock mass airflow sensor in circuit, so installation can typically be completed in 90 minutes or less with only basic hand tools. Published details vary across sources on both model years and install time, so confirm your truck's year and the install sheet with the manufacturer before ordering. The reusable filter is the long-term payoff: the filter only requires cleaning every 100,000 miles under normal highway driving conditions, which helps offset the cost of a stock-style replacement cycle. Search terms this part answers include 2015-2016 Ram 1500 EcoDiesel cold air intake, K&N 57-1571 FIPK, and 3.0L EcoDiesel reusable air filter.
The manufacturer says the kit replaces the factory air filter and intake tube, while the heat shield installs onto the lower factory air box and retains the fresh air inlet. The lower airbox stays in use.
Yes. The manufacturer states the kit incorporates the factory mass air sensor, so the sensor does not need to be relocated or replaced.
The manufacturer's figures come from a single chassis dyno test on a 2015 Ram 1500 3.0L EcoDiesel, showing roughly 188 hp stock versus roughly 199 hp with the kit at 3,300 rpm. Results on other trucks may differ.
This is a moderate DIY job that the manufacturer describes as doable with basic hand tools, with install time quoted anywhere from 60 to 90 minutes. The kit uses the truck's existing factory mounting points, so no custom brackets are needed. Before you start, download the manufacturer's installation instruction sheet and confirm your model year matches the 2015-2016 application. Leave the heat shield mounted to the lower factory airbox, since it protects the filter from engine-bay heat. Keep the mass airflow sensor connector fully seated, and check all clamps are tight before starting the engine.
