The K&N 57-1517-2 is a 57 Series FIPK cold air intake for V8 Dakota and Durango trucks and SUVs from 2000 through 2003. The roto-molded HDPE tube is paired with an oversized oiled cotton air filter, and a custom heat shield helps protect intake air from engine bay heat. Because it replaces the factory airbox and intake tube, it is a full system rather than a drop-in filter.
The purchase case rests on more than the filter. The manufacturer lists an estimated torque gain of 13.5 lb-ft, and the kit is legal for use in all 50 states. Expectations should stay realistic: owners on user forums describe mixed results, with some reporting a noticeable pull after swapping to a K&N filter and others finding the gain modest and mostly audible. Search terms like 2003 Dakota 5.9 cold air intake, Durango 5.2 FIPK install, and 57-1517-2 washable filter cleaning will match this kit's specific use case.
The manufacturer's installation sheet states the kit was not designed to fit vehicles with a body lift.
The manufacturer says the filter only requires cleaning about every 100,000 miles under normal highway driving conditions.
The manufacturer notes that disconnecting the negative battery cable erases preprogrammed electronic memories, so record radio and memory settings beforehand. Some radios may require an anti-theft code after reconnection.
The manufacturer describes installation as achievable in 60 minutes or less with simple hand tools, and the kit uses the factory mounting points. Time estimates vary across published sources, so confirm against the manufacturer's installation sheet before scheduling a weekend. Start by disconnecting the negative battery cable and writing down radio and memory settings. Use only the hardware supplied with the kit: the manufacturer warns that skipping the provided hardware can damage the intake tube, throttle body, or engine. Confirm the kit is not being mounted on a body-lifted truck, and recheck clamps and connections after installation.
