The engine that powers your Mercedes-Benz vehicle needs a steady supply of both oxygen and fuel to feed combustion. Your air intake system, some refer to as an air induction system, is responsible for delivering the air part of that mixture.

How it works is simple. First, the intake manifold pulls outside air through an air filter, which captures airborne contaminants and dust. Next, three components work together to determine the proper amount of air needed for ideal combustion.

A mass airflow sensor measures the air's movement, while an air metering system delivers feedback regarding the amount of air being used to an engine control unit, or ECU. Lastly, an oxygen sensor monitors the exhaust levels, so that the engine can adjust both fuel and air levels to maintain an optimized mix.
