Bosch Mass Air Flow (MAF) Sensor for Mercedes-Benz — 0280218190 OE Replacement, Pre-Calibrated Durable Design

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

This Bosch MAF sensor is designed and manufactured to OE specifications, providing calibrated sensor-and-housing accuracy, rugged protection against moisture and particulates, and connector and mounting geometry that match factory originals. Because Bosch supplies many automakers with original components, this part reproduces the calibration and fitment engineers expect, making it a straightforward replacement when diagnostics point to an air-flow measurement issue.

How does this MAF sensor affect engine performance and fuel economy?

The MAF sensor measures the mass of incoming air to help the engine control unit (ECU) calculate correct fuel delivery. A precise signal reduces rich or lean running conditions, which improves throttle response and can reduce fuel consumption compared with a failing sensor. Bosch cites up to 20% better fuel consumption versus poorly performing sensors when the air measurement is corrected.

• Improved air-to-fuel ratio accuracy for smoother idling and acceleration
• Reduced risk of drivability problems caused by incorrect air readings
• Potential fuel economy gains when replacing a degraded sensor
• Helps maintain emissions targets by giving the ECU correct input

What makes Bosch's design more durable than aftermarket options?

Bosch MAF sensors use a patented design focused on robustness and long-term stability. That design reduces sensor drift, lowers pressure drop in the intake tract, and offers improved resistance to water and particle contamination compared with generic remanufactured units.

• Patented protective geometry to limit contaminant exposure
• Calibrated sensor and housing assembly to prevent mismatches
• All-new components (not remanufactured) for longer service life
• OE-grade connectors and attachment points for proper sealing and fit

How simple is installation and vehicle fitment?

Installation is typically quick because Bosch reproduces OE connector pins and mounting locations, allowing the sensor to drop into the factory intake housing with no modifications. For selective part numbers, the sensor is supplied pre-calibrated with its housing so you install a matched assembly rather than mating separate parts.

• OE-identical connector and mounting for a direct swap
• Pre-calibrated sensor-plus-housing options eliminate reprogramming
• Installation generally takes minutes with basic hand tools
• Always confirm vehicle compatibility using the fitment checker

Which vehicles is part number 0280218190 compatible with?

0280218190 is compatible with a range of Mercedes‑Benz gasoline models across several years. Confirm fitment against your VIN or use the online fitment tool before ordering, since Bosch supplies multiple housings and calibration variants for different engines and intake designs.

• Common fits include C‑Class, E‑Class, S‑Class, SLK, SL, CL, CLS and GL/ML family models
• Years represented include mid-2000s through early‑2010s Mercedes‑Benz models
• Specific models: C230, C250, C280, C300, C350, CL550, CLK350, CLK550 and others
• Verify exact engine and model year compatibility before purchase

Who is this for: technicians, DIY mechanics, and Mercedes‑Benz owners seeking a direct OE-quality replacement sensor to address MAF-related faults, restore correct air measurement, and prolong engine and emissions-system performance. Choose this Bosch part when you want a brand-new, factory-calibrated assembly with OE fit, proven durability, and the peace of mind that comes from a global original-equipment supplier.
