  • Hesitation or stumble during acceleration
  • Lean or rich air/fuel mixture concerns
  • Check engine light conditions related to mass air flow sensor output
  • Driveability issues tied to contaminated or failing MAF sensors

Installation Notes and Quality Assurance

Verify the connector style, bolt pattern, and housing configuration before installation. Clean the intake tract and inspect the air filter and ducting so the new sensor is not exposed to debris or oil contamination. Standard Ignition manufactures this MAS0128 sensor to strict quality standards and computer-tests each unit to confirm accurate signal output for the ECU.

For Ford F-150, Taurus, Crown Victoria, and Mercury Cougar applications, MAS0128 provides a direct-fit replacement path with the correct electrical and mounting layout.
