Description
Product Overview
The YAOPEI Mass Air Flow (MAF) Sensor is a precision‑engineered component designed specifically for a range of BMW 3.0L engines, including the 128i, 328i, 528i, and related xDrive variants. Constructed from high‑quality silicone‑coated ceramic PC boards, the sensor offers exceptional wear resistance and stability under extreme temperature fluctuations. The internal silicon chip is protected by a durable silicone layer, ensuring long‑term reliability even in harsh engine bays. With dimensions of 3.74 x 3.23 x 2.95 inches and a lightweight design of just 2.08 ounces, the sensor integrates seamlessly into the existing air intake system without adding unnecessary bulk.
Beyond its robust construction, the YAOPEI MAF sensor features a calibrated airflow measurement range that matches the original equipment specifications. This ensures that the engine control unit (ECU) receives accurate data for optimal fuel injection timing, ignition timing, and emissions control. The sensor’s design also incorporates a low‑profile connector that simplifies wiring and reduces the risk of pin damage during installation. As a direct replacement for part numbers 13627551638, 5WK97508Z, 74-50082, and MAS0287, it guarantees a perfect fit and eliminates the need for custom modifications.

Usage
This MAF sensor is ideal for both professional mechanics and DIY enthusiasts who are looking to restore or upgrade the performance of their BMW 3.0L powerplants. It excels in environments where precise airflow measurement is critical, such as high‑performance driving, track days, and long‑distance touring. By delivering reliable data to the ECU, the sensor helps maintain smooth idle, responsive throttle, and consistent power delivery across a wide range of operating conditions.
Before installation, it is recommended to clean the air box and replace the air filter to prevent contaminants from triggering error codes. The sensor’s plug‑and‑play design means it can be installed in under an hour with basic hand tools. Once fitted, drivers will notice improved fuel efficiency, reduced engine strain, and a noticeable decrease in the frequency of check‑engine lights related to airflow anomalies.
