Detailed Description
Delphi AF10404 is a mass air flow sensor engineered for 2008-2009 Saturn Astra applications. It is built as a complete assembly with the housing included, a single rectangular connector, and blade-style terminals for a factory-style electrical interface. If you are replacing a worn or failing MAF sensor on a Saturn Astra, this part number AF10404 provides the correct form factor for the listed vehicle fitment. Delphi AF10404 also cross-references Standard Ignition MAS0273 for the same application.
Delphi draws on OE-level knowledge from supplying major automakers, and that experience is reflected in the fit, connector design, and replacement-focused construction of this sensor. For buyers searching for a 2008 Saturn Astra mass air flow sensor or a 2009 Saturn Astra MAF sensor, AF10404 is the direct-fit option to compare against the original unit.
What It Helps Fix
- Rough idle caused by inaccurate airflow readings
- Hesitation or stumble during acceleration
- Check engine light related to air metering faults
- Poor fuel trim behavior from a failing sensor
- Driveability issues tied to contaminated or aging MAF components
Installation Notes
Verify the connector shape, terminal count, and mounting style before installation. This sensor uses a band clamp mount and does not include a wiring harness. Follow the included instruction sheet and inspect the intake tube and electrical connector for damage or contamination before fitting the new unit.
Quality Assurance
Delphi builds this replacement sensor using OE-based engineering knowledge developed through decades of original equipment supply. The AF10404 is a standard replacement part intended to match the listed Saturn Astra applications with the correct sensor configuration and assembly details.
