Beck/Arnley 158-1603 Air Mass Sensor OE Replacement MAF Sensor

The Beck/Arnley 158-1603 is a direct-fit OE replacement air mass sensor (MAF sensor) engineered specifically for foreign nameplate vehicles. Designed to match original equipment specifications for form, fit, and function, this sensor restores accurate airflow measurement to the engine management system, ensuring proper fuel delivery and optimal engine performance.

The mass air flow sensor plays a critical role in engine operation — it continuously measures the volume and density of air entering the intake, relaying that data to the ECU so the correct air-to-fuel ratio can be maintained. A faulty or failed MAF sensor can cause rough idle, poor fuel economy, hesitation, and illuminated check engine lights.

Key Features:

• Matches OE form, fit, and function for a hassle-free installation
• Corrosion-resistant terminals and protective coatings for long-term durability
• Engineered to withstand harsh under-hood temperatures and engine environments
• May include or exclude housing depending on original equipment design
• Sourced through Beck/Arnley's global network of OE-quality suppliers
• Application-specific design — no modifications required

Beck/Arnley specializes exclusively in parts for foreign nameplate vehicles, and their product specialists verify every part against OE standards before it enters the lineup. The 158-1603 air mass sensor is a reliable, confidence-inspiring replacement backed by Beck/Arnley's trusted quality assurance process.
