One of AFE Power’s best-known products is the AFE cold air intake system, designed to increase airflow and improve combustion efficiency. With options for both open and closed systems, AFE cold air intakes are built to optimize horsepower and throttle response. For those aiming to push their trucks to the limit, these intakes provide the airflow needed for consistent, powerful performance.

AFE filters are made with various filter media to suit different driving environments. Choose from the Pro 5R, Pro 10R, Pro-GUARD 7, and Pro DRY S filters to achieve the right balance of airflow and filtration. Engineered with multiple layers of protection, AFE filters capture finer debris while maintaining excellent airflow, extending your engine's life and efficiency.

Upgrading to an AFE Power exhaust system reduces backpressure and increases exhaust flow, allowing for improved performance and fuel efficiency. Built with premium materials, these exhausts provide a deeper sound without compromising factory emissions. AFE Power’s exhaust options help you achieve a cleaner, more efficient burn while adding an aggressive tone to your truck’s performance.
