Product Overview

The K&N 57-1532 Performance Intake System is designed to unlock the hidden power in your 2003–2007 Dodge Ram 2500 or 3500 with the 5.9L Cummins diesel. This FIPK (Fuel Injection Performance Kit) replaces the restrictive factory air intake with a rotationally-molded HDPE intake tube and a massive RE-4780 air filter, improving airflow efficiency while maintaining strong filtration.

The result? A dyno-proven +10.96 horsepower gain, improved throttle response, and better breathing under heavy loads or hard acceleration.

Ideal for daily-driven trucks, weekend towers, or workhorse diesels, the 57-1532 includes everything needed for installation—from premium clamps to mounting hardware—and does not require ECU tuning. The oversized cotton filter can go up to 100,000 miles between cleanings, making this kit as easy to maintain as it is to install.
