Bosch 077-133-471 J Mass Air Flow Sensor MAF

The Bosch 077-133-471 J is an original equipment mass air flow (MAF) sensor designed to deliver precise air measurement for optimal engine performance. As a global leader in mass air flow technology, Bosch MAF sensors ensure low levels of harmful emissions with greater fuel efficiency and improved engine performance.

Key Features:

• Patented design increases robustness against water and particulate damage, reduces sensor drift, and lowers pressure drop
• 100% new sensor - not remanufactured - ensuring highest quality and longest life
• OE experience and superior technology provides correct function and calibration to match vehicle requirements
• OE identical connector ports and attachment points ensure exact fit and trouble-free installation
• Ensures low harmful emissions with up to 20% better fuel efficiency and improved engine performance
• Direct replacement for OEM part number 077 133 471 J

Signs of a failed mass airflow sensor may include rough idle, rise in fuel consumption, increased harmful emissions, and poor drivability. This genuine Bosch sensor restores proper engine management system function by accurately measuring air mass flow independent of density and temperature, ensuring your engine receives the correct air-fuel mixture for optimal combustion.
