Performance Intake Kit Ram 2500/3500

The K AND N ENGINEERING Performance Intake Kit for Ram 2500/3500 (model 57-1557) is a cold air induction system engineered for full-size Dodge Ram trucks from 2007–2009. This FIPK (Fuel Injection Performance Kit) replaces the factory restrictive air box with a direct intake pathway, allowing cooler, denser air into the engine's intake manifold. Built for truck owners and mechanics seeking measurable improvements in throttle response and overall engine efficiency, this kit addresses a fundamental limitation in OEM intake design—inadequate airflow volume and elevated intake temperatures under load.

The 57 Series system features K AND N's signature reusable, high-flow air filter element, which delivers superior filtration while maintaining minimal restriction compared to paper disposable filters. The kit's mandrel-bent intake tubing is sized to maximize velocity and reduce turbulence, drawing air from a lower, cooler source than stock designs. The reusable filter can be cleaned and re-oiled multiple times over its lifespan, making this a cost-effective long-term investment for high-mileage trucks. Weighing 14.9 lbs and engineered to fit within factory engine bay dimensions (18.1 x 12.6 x 18.4 inches), installation requires no modifications to the truck's frame or body, though mechanical competency is recommended for proper fitment and sensor connections.

Ram 2500 and 3500 owners who regularly tow, haul, or operate in high-temperature conditions see the most tangible benefits, as cooler intake air improves combustion efficiency and reduces heat stress on the engine during sustained load. This kit is compatible exclusively with 2007–2009 Dodge Ram full-size trucks and should be paired with a tune or baseline ECU calibration if maximum potential is desired. Installation typically takes 1–2 hours and requires basic hand tools; no cutting or welding is necessary. For fleet operators or owner-operators managing multiple trucks, the durability and washable filter design delivers maintenance simplicity and lower consumable costs over the life of the vehicle.
