Standard Ignition MAS0237 mass air flow sensor for the 1998-1999 BMW 323i 6-cylinder 2.5L and other vehicles measures the air entering the engine. It reports that reading to the computer, which uses it to balance the air/fuel ratio.
- 100% computer-tested so the ECU receives accurate airflow readings under hard engine conditions
- Designed to help improve engine performance, reduce harmful emissions and increase fuel efficiency
- Manufactured and calibrated to strict quality standards
- Round female connector with four male bullet terminals
