Bosch MAF Sensor 0280218190 — OE Mass Air Flow Sensor for Mercedes‑Benz, Exact‑Fit New

Bosch 0280218190 is a 100% new original-equipment mass air flow (MAF) sensor engineered to restore accurate air measurement, improve engine responsiveness, and maintain emissions compliance for compatible Mercedes-Benz models.

This Bosch OE MAF sensor replaces the factory unit with exact-fit connectors, precise calibration, and a robust design built to resist moisture and contaminants. Because the sensor and housing are calibrated together (when applicable), installation is straightforward and readings are reliable from the first start. Bosch supplies new, not remanufactured, MAF sensors which help preserve fuel economy and engine control performance across the listed vehicle applications.

How does the Bosch 0280218190 affect fuel economy and emissions?

Accurate airflow measurement helps the engine control unit calculate correct fuel delivery. Replacing a failing MAF with this Bosch OE sensor reduces the risk of overfueling or lean conditions that can raise emissions and lower MPG.

• OE-grade calibration for correct air-to-fuel calculations
• Patented design reduces sensor drift to keep readings stable over time
• Lower pressure drop preserves engine breathing and efficiency
• Can help return fuel consumption toward factory specifications

What makes this Bosch sensor more durable than aftermarket options?

Bosch builds its OE MAF sensors with extra protection against water and particulates and uses materials and tolerances matched to original vehicle standards. The result is a longer-lasting sensor with fewer false readings and less frequent replacement.

• Patented housing design improves resistance to moisture ingress
• Reduced susceptibility to particulate contamination and drift
• Sold new (not remanufactured) for consistent, predictable life span
• OE-identical connector and mounting for secure, vibration-resistant fit

Is installation complicated and will it fit my Mercedes-Benz?

Installation is typically quick because Bosch OE sensors match original connector ports and attachment locations. Always verify fitment against your vehicle’s year and model using the fit checker before ordering.

• Exact-fit OE style connectors for plug-and-play replacement
• Sensor and housing calibrated together for some part numbers—photo will show included housing
• Fits a range of Mercedes-Benz models (see fitment list) — confirm specific application before purchase
• Simple swap that generally requires only basic hand tools

How will I know if my MAF sensor needs replacement?

Symptoms of a failing MAF include rough idle, hesitation on acceleration, decreased fuel economy, or check engine light codes related to airflow. Replacing a faulty sensor with a Bosch OE unit restores accurate measurements and often resolves these drivability issues.

• Check engine light with airflow or fuel-trim related diagnostic codes
• Noticeable drop in MPG or rough engine operation under load
• Surging or hesitation during acceleration
• Professional diagnostics can confirm sensor readings and airflow accuracy

Who is this for: This Bosch 0280218190 MAF sensor is intended for owners, technicians, and restoration specialists working on compatible Mercedes‑Benz models who want a direct OE replacement. It suits anyone seeking factory-grade calibration, durable construction, and an easy install to restore proper engine management and emissions performance.
