Bosch Mass Air Flow Sensor 0280218390 Flange Mount High Accuracy MAF

Description

Product Overview

The Bosch Mass Air Flow (MAF) Sensor model 0280218390 is engineered to deliver precise airflow measurement for internal combustion engines. Built with a machined exterior and a patented flange‑mount design, the sensor offers superior resistance to water ingress and particulate contamination, which are common challenges in high‑performance automotive environments. Measuring dimensions of 6.02 x 4.92 x 4.61 inches and weighing only 0.33 kilograms, the unit combines compact size with robust construction. The sensor utilizes a push‑pull output type, providing reliable voltage signals that translate directly into accurate air mass calculations for the engine control unit. Its very good measurement accuracy ensures that fuel injection timing is optimized, resulting in smoother engine operation, reduced emissions, and improved fuel economy. The OEM part numbers 07C906461 and 95560612300 confirm its compatibility with original equipment specifications, making it a seamless replacement for factory‑installed components.

Usage

Designed for a wide range of automotive applications, this MAF sensor is ideal for both daily drivers and performance‑oriented vehicles. It fits select Porsche models from 2003‑2006 Cayenne and various Volkswagen platforms, including Beetle, Rabbit, and Phaeton series. The sensor’s flange‑mount installation simplifies the replacement process: align the mounting holes with the engine bay, secure the sensor with the supplied bolts, and connect the OE‑identical plug without the need for additional adapters. Once installed, the sensor continuously monitors incoming air, allowing the engine control module to adjust fuel delivery in real time. This real‑time adjustment is especially beneficial during rapid throttle changes, high‑altitude driving, and cold‑start conditions where precise air‑fuel ratios are critical. The sensor’s durability also makes it suitable for off‑road and rally environments where exposure to dust and moisture is frequent.

FAQ

What vehicles are compatible with this Bosch MAF sensor?

The sensor is compatible with a range of Porsche and Volkswagen models, including the 2003‑2006 Porsche Cayenne, 2006‑2010 Volkswagen Beetle, 2004‑2006 Volkswagen Phaeton, and several other variants. Compatibility depends on engine type and trim level, so it is recommended to verify fitment using the vehicle’s VIN or the fit‑checker tool on the retailer’s website.

How does the flange‑mount design improve durability?

The flange‑mount design incorporates a sealed housing that shields the internal sensing element from moisture, dust, and road debris. This protection reduces the likelihood of sensor drift and failure, especially in environments with frequent exposure to water splashes or off‑road conditions.

Is calibration required after installation?

No additional calibration is needed. The sensor is calibrated at the factory to match OEM specifications, and the OE‑identical connector ensures the engine control unit receives accurate data immediately after installation.

What warranty does Bosch provide for this sensor?

Bosch offers a limited warranty that covers manufacturing defects for a period of one year from the date of purchase. The warranty also includes technical support for installation assistance and performance verification.

Can this sensor improve my vehicle’s performance?

By delivering precise airflow data, the sensor enables the engine control unit to fine‑tune fuel delivery, which can lead to smoother acceleration, better throttle response, and up to 20% improvement in fuel efficiency compared to a faulty or outdated MAF sensor.
