Overview

It is an OEM (Original Equipment Manufacturer) part from Bosch, ensuring compatibility and performance.
Show original supplier description
The Bosch Mass Air Flow Sensor is a direct replacement for your BMW's original equipment. This hot wire sensor accurately measures incoming air volume, providing critical data to the Engine Control Unit (ECU) for precise fuel injection and ignition timing. Over time, MAF sensors can degrade, causing issues like rough idle, stalling, poor fuel economy, and illuminated check engine lights. Symptoms of a failing MAF sensor include OBD-II codes related to MAF faults, inconsistent fuel trims, and a generally rich or lean running condition. This Bosch MAF sensor is specifically designed for the BMW M5 (E39) and Z8 (E52) models equipped with the S62 5.0L V8 engine. It is engineered as a "hot wire" type sensor and features a self-cleaning function to maintain accuracy. The product is listed with OE numbers 13621433566 and 0280217533. This mass air flow sensor is compatible with the following BMW vehicles: * **BMW M5:** 1999-2003 (E39) with S62 5.0L V8 engine (Manual RWD Sedan) * **BMW Z8:** 2000-2003 (E52) with S62 5.0L V8 engine (Manual RWD Convertible) It is important to ensure this part is compatible with your specific vehicle's year, model, and engine configuration.
