Air cleaner

The air cleaner, which is located on the right-hand side of the engine bay, removes particles from the intake air and also acts as an intake silencer.

Mass air flow sensor

The mass air flow sensor provides the engine control module with continuous information on the air mass consumed by the engine. The mass air flow sensor signals are processed by the control module, which monitors the fuel-air mixture needs of the engine.

For more information on the mass air flow sensor, refer to ENGINE MANAGEMENT SYSTEM, TRIONIC T8 -- 9-3 (2006) or ENGINE MANAGEMENT SYSTEM, TRIONIC T8 (2007) .

For more information on turbocharging, refer to TURBOCHARGER SYSTEM .
