The K&N AirCharger Intake System for the 2007.5–2009 Dodge/Ram 2500 & 3500 6.7L Cummins diesel is a high-performance air intake upgrade designed to replace your factory air filter and intake housing with a free-flowing, high-flow intake that helps your engine breathe better. These systems use washable, reusable high-flow filter media and are engineered to dramatically reduce intake restriction, allowing more air into the engine for improved combustion efficiency, horsepower, and torque.
Key Features
- 57 Series / 63 Series FIPK Design: The K&N AirCharger system (such as the 57-1557 or 63-1557 variants) uses a high-flow filter and smooth intake path to increase airflow and performance.
- Washable & Reusable Filter: The washable high-flow filter helps reduce maintenance costs over time and provides long service life.
- Performance Gains: K&N claims these intake systems can increase power by as much as ~10% over stock by reducing restriction and smoothing airflow into the turbo.
- Easy Installation: Designed as a direct replacement for the factory intake components with basic hand tools.
- Street Legal: Many K&N AirCharger systems for this application are CARB exempt / street legal in all 50 states, making them suitable for daily-driven trucks.
Benefits
- Increased Airflow: More air to the turbocharger can improve throttle response and power delivery.
- Reusable Filter: Washable filter element means lower long-term maintenance costs.
- Better Engine Sound: Many owners report a more aggressive intake sound under acceleration (common with high-flow intakes).
