Bosch 0280218386 Mass Air Flow MAF Sensor

The Bosch 0280218386 is an Original Equipment (OE) Mass Air Flow (MAF) sensor designed for select Porsche models including 911, Boxster, and Carrera GT. This sensor measures the amount of air entering the engine and communicates with the ECU to precisely match fuel injection for optimal power and efficiency.

Key Features:

• 100% new sensor (not remanufactured) ensuring highest quality and longest service life
• Patented design increases robustness against water and particulate damage while reducing sensor drift
• OE technology provides correct function and calibration for trouble-free operation and emissions compliance
• Delivers up to 20% better fuel efficiency with reduced harmful emissions
• Pre-calibrated sensor and housing sold together for precise readings and simple installation
• OE identical connector ports and attachment points ensure exact fit

A faulty MAF sensor can cause excessive fuel consumption, rough engine operation, stalling, and trigger the check engine light. This Bosch replacement restores proper engine management system functionality. Cross-references to Porsche OEM part number 98660612502.
