Upgrade your 2006–2007 LBZ Duramax with the K&N AirCharger Intake System (57-3057), engineered to increase airflow, improve throttle response, and deliver reliable horsepower and torque gains. This system replaces the restrictive factory air intake with a high-flow design that allows your engine to breathe more efficiently for improved overall performance.
The AirCharger system features a roto-molded intake tube designed to smooth and straighten airflow into the turbo, reducing restriction and improving engine efficiency. Paired with a high-flow, washable oiled cotton air filter, this intake provides excellent filtration while maximizing airflow for long-term performance and durability.
A custom heat shield helps reduce the impact of engine bay heat by directing cooler outside air into the intake system, improving air density and combustion quality. The result is stronger acceleration, improved throttle response, and a more aggressive intake sound under load.
Built as a direct bolt-on replacement, this system installs easily using basic hand tools with no major modifications required.
Key Features:
- Increases horsepower, torque, and throttle response
- High-flow roto-molded intake tube for improved airflow
- Washable and reusable oiled cotton air filter
- Heat shield design helps reduce intake air temperatures
- Improves engine efficiency and reduces airflow restriction
