The function of the air induction system is to sieve, meter, and gauge air flow into the engine. Filtered air moves into the intake manifold in various volumes. The volume of air entering the engine is a function of throttle valve opening angle and engine rpm. Air speed is elevated as it passes through the long, narrow intake manifold runners,
leading to improved engine volumetric efficiency.
Air intake systems allow engines to breathe more freely, making more horsepower and
higher gas mileage. Air intake systems have diverse styles to choose from,
such as Cold Air Intake systems Stage 1, Stage 2, Intake Manifolds, Upgrade Tubes,
Super Stock Induction, Universal Stage 1xp, Torque Booster Tubes, Charged Air
Manifolds and Throttle Body Spacer.
Similar to clean lungs, engines are guaranteed to show performance increases with an aFe Air Intake.
