The Air Induction System (AIS) on Ford trucks equipped with the 7.3-liter Power Stroke diesel engine is a component designed to provide cooler, denser air to the engine for combustion. This system typically replaces the factory air box and filter, aiming to improve airflow and filtration. A common example involves aftermarket upgrades featuring larger filter elements and redesigned intake tubes.
Optimizing airflow to the 7.3L Power Stroke enhances engine performance through increased horsepower and torque. The denser air charge achieved by these systems can also contribute to improved fuel economy and reduced exhaust gas temperatures (EGTs), mitigating the risk of engine damage under heavy loads. The development of these systems coincided with the growing popularity of diesel truck modifications aimed at improving power and reliability.
