Bosch F026400133 Air‑Filter Insert

The Bosch F026400133 Air‑Filter Insert is a high‑performance component designed to protect the engine of Mercedes‑Benz vehicles from contaminants while ensuring optimal airflow. This insert is engineered for the C‑Class (W204), E‑Class (W212), and GLK‑Class (X204) models, as well as their T‑model variants such as the C‑T (S204). It is available in a range of sizes to accommodate different engine configurations, including 180D, 200D, 220 CDI, and 250 CDI powertrains.

Key Features

• Premium Filtration Media: Utilizes Bosch’s proprietary multi‑layer media that captures fine dust, pollen, and road grime while maintaining low resistance to airflow.
• Extended Service Life: Designed for up to 30,000 km (or 2 years) of service life under normal driving conditions, reducing the frequency of filter changes.
• Seamless Fitment: The insert is engineered to fit directly into the existing Bosch air‑filter housing without modification. It aligns with the standard S0133 mounting system.
• Durable Construction: Made from high‑quality, heat‑resistant polypropylene that withstands engine bay temperatures and protects against oil vapor infiltration.
• OEM Quality Assurance: Meets or exceeds Mercedes‑Benz OEM specifications for filtration efficiency, pressure drop, and durability.

Compatibility Overview

The F026400133 insert is compatible with a wide array of Mercedes‑Benz models. Below is a concise compatibility matrix:

For any other Mercedes‑Benz variants, consult the official Bosch catalog or a certified service center to confirm fitment.

Installation Procedure

1. Preparation: Park the vehicle on a level surface, engage the parking brake, and disconnect the battery for safety if required by your maintenance protocol.
2. Accessing the Air‑Filter Housing: Remove the outer cover of the air‑filter housing. This typically involves unscrewing a few bolts or releasing clips that hold the cover in place.
3. Removing the Old Filter: Carefully lift out the existing filter cartridge. Dispose of it according to local environmental regulations.
4. Installing the Insert: Place the F026400133 insert into the housing, ensuring that the orientation matches the airflow direction indicated on the housing or the insert itself.
5. Securing the Housing: Replace the outer cover and re‑tighten all fasteners. Verify that the seal is intact to prevent air leaks.
6. Final Check: Reconnect any electrical connectors if applicable, start the engine, and listen for any abnormal noises indicating a loose fit.

Performance Benefits

• Improved Engine Efficiency: By maintaining clean air intake, the filter helps preserve optimal combustion efficiency and reduces fuel consumption.
• Enhanced Longevity: Protects internal engine components from abrasive particles that could cause wear or damage over time.
• Consistent Airflow: The low pressure drop design ensures that the engine receives sufficient air volume, which is critical for high‑performance and turbocharged units.
• Reduced Maintenance Costs: Longer service intervals mean fewer visits to a mechanic or dealership for filter replacement.

Quality Assurance & Compliance

The F026400133 insert undergoes rigorous testing in accordance with Bosch’s global quality standards. It is validated against:

• ISO 9001:2015 – Quality Management Systems
• ISO/TS 16949 – Automotive Sector Specific Requirements
• Mercedes‑Benz OEM specifications for filtration efficiency and durability.

Maintenance Tips

• Inspect the filter every 15,000 km or after exposure to dusty environments such as construction sites or unpaved roads.
• Avoid using compressed air directly on the filter media; instead, use a soft brush or vacuum cleaner with a HEPA filter attachment.
• If the filter becomes visibly clogged or discolored, replace it immediately to prevent airflow restriction.

Conclusion

The Bosch F026400133 Air‑Filter Insert represents an essential component for Mercedes‑Benz owners who demand reliability, performance, and longevity from their vehicles. Its OEM‑grade construction, proven compatibility across multiple model lines, and user‑friendly installation make it a top choice for maintaining engine health and ensuring optimal driving experience.
