Spectra MA173 Premium Mass Air Flow Sensor with Housing

The Spectra Premium MA173 is a 100% new mass air flow (MAF) sensor designed and engineered to meet or exceed Original Equipment (OE) specifications. Built without the need for a core charge, this sensor delivers reliable, precise airflow measurement to keep your engine's fuel-air ratio calibrated for optimal performance.

Key Features:

• OE-Quality Ceramic Circuit Board – Features a ceramic PC board with superior heat dissipation properties for consistent voltage output and long-term performance stability
• Premium Silicon Coating – Protects internal components from severe under-hood temperature fluctuations and road vibration
• Platinum Resistance Thermometer Sensors – All-new platinum RTD elements provide faster signal response and improved measurement consistency
• Dust-Free Manufacturing – Precision electronic components assembled in a controlled, contamination-free environment
• ISO 9001 & TS16949 Certified – Manufactured under rigorous quality management standards covering raw materials, in-process controls, and final inspection
• Extensive Computerized Testing – Each unit undergoes real-world performance validation before leaving the facility
• No Core Charge Required – Completely new unit; no exchange or return of old part necessary
• Limited Lifetime Warranty – Backed by Spectra Premium's limited lifetime warranty against defects in materials and workmanship

A failing mass air flow sensor can cause rough idle, reduced fuel economy, and long-term damage to oxygen sensors, spark plugs, and catalytic converters. The Spectra Premium MA173 restores accurate airflow readings and is engineered for a direct, drop-in installation with no modifications required.
