Keep your engine's air metering accurate with the Hitachi Astemo Mass Air Flow Sensor MAF0031 — a NEW, actual OE-grade sensor that measures the amount and characteristics of air entering the engine so the ECU can meter fuel correctly. It's a direct-fit replacement for a long list of Infiniti and Nissan applications, including the 2003-2008 INFINITI G35 [V6-3.5L], 2008-2013 INFINITI G37 [V6-3.7L], 2009-2019 NISSAN 370Z [V6-3.7L], 2004-2013 NISSAN ALTIMA [L4-2.5L], and 2005-2014 NISSAN FRONTIER [L4-2.5L]. See the Buyer's Guide tab for the full 76-application list and engine codes.

  • Calibrated & tested: 100% air-flow tested and calibrated for each application, built with precision elements and high-quality components.
  • Contaminant bypass port (where applicable): supports reliable operation and helps extend service life.
  • Welded connections are used instead of soldered joints for dependability.
  • Meets the OE performance and durability standards for this application.

Fitted with 5 blade terminals. Wiring harness is not included and housing is not included. Country of origin: United States. If a failed mass air flow sensor is the cause of rough idle, hesitation, or poor fuel economy, this unit replaces it — diagnose the cause before replacing.
