Detailed Product Overview

The MAS0161 mass air flow sensor measures incoming air so the engine control system can calculate fuel delivery and maintain proper drivability. This Standard Ignition replacement is built as a complete assembly, which helps simplify service when replacing a worn or contaminated MAF sensor on Mercedes-Benz G55 AMG, E320, ML320, SL500, and related models, as well as the Chrysler Crossfire. Standard Ignition MAS0161 is a direct-fit emission control sensor for vehicles that use the specified connector and mounting style.

Common Problems This Part Can Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to mass air flow sensor performance
• Poor fuel trim behavior from a contaminated or failing sensor
• Hard starting or inconsistent throttle response

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. Inspect the intake tract for air leaks, loose clamps, or contamination that could affect sensor readings. If the original sensor housing is damaged or the element is contaminated, replacing the assembly can help restore proper airflow measurement. Confirm fitment by year, make, and model before ordering; this part is listed for 1998-2010 Mercedes-Benz applications and 2004-2008 Chrysler Crossfire models in the provided fitment data.

Quality Assurance

Standard Ignition supplies emission control sensors for direct replacement service, and MAS0161 is cataloged as a complete assembly for the listed applications. Use the confirmed vehicle fitment and connector specifications to match the correct part before installation.
