Spectra MA338 Mass Air Flow Sensor

Spectra MA338 Mass Air Flow Sensor

The Spectra MA338 mass air flow sensor is a direct-fit emission control sensor for select Nissan and INFINITI applications. It is built with a programmable ceramic circuit board and premium-grade silicon coating to help protect the sensor from under-hood heat swings and road vibration.

Fits 1989-1999 Nissan Maxima, N/A. Fits 1990-1992 INFINITI M30, N/A.

Key Features

• Mass air flow sensor with integrated housing application
• Programmable ceramic circuit board for stable signal output
• Premium-grade silicon coating for added protection against temperature fluctuation and vibration
• Platinum resistance thermometer sensor design for faster signal response
• OE-style replacement for emission control system service

Detailed Description

Built for air metering accuracy, the Spectra MA338 helps the engine control module measure incoming air so fuel delivery can stay properly calibrated. This part cross-references Delphi AF10210 and Four Seasons 59086 for the same application. It is a fit for Nissan Maxima and INFINITI M30 models listed above, making it a practical replacement when servicing the intake and emission control system.

The MA338 is a useful search match for drivers looking for a Nissan Maxima mass air flow sensor with integrated housing or an INFINITI M30 MAF sensor replacement. The part number MA338 also helps confirm the correct sensor when comparing listings and interchange references.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to air metering faults
• Poor fuel control from a failing mass air flow sensor
• Driveability issues tied to contaminated or worn sensor elements

Installation Notes and Tips

Verify the connector style, housing configuration, and vehicle application before installation. Inspect the intake tract for leaks, damaged wiring, or contamination that could affect sensor readings. After replacement, clear diagnostic trouble codes and confirm proper idle and throttle response.

Quality Assurance

Spectra uses a ceramic circuit board with protective silicon coating and platinum resistance thermometer sensor technology to support consistent signal response in demanding under-hood conditions.
