Mann Filter Engine Air Filter C 28 004 for Mercedes C/E/GLC/SLC — OE-fit, High‑Efficiency Particle Separation

The Mann Filter C 28 004 is a vehicle-specific engine air filter engineered to protect your Mercedes-Benz engine by providing high-efficiency particle separation and stable airflow.

When maintaining modern Mercedes-Benz engines, clean intake air is essential for consistent performance and component longevity. The Mann Filter C 28 004 replaces worn or clogged air filters with an OE-fit element that keeps harmful particles out of the combustion chamber, helps preserve the mass air flow sensor, and resists moisture and hot ash with its treated media. Built with embossed pleats for dimensional stability, this filter balances low airflow resistance with high dirt-trapping capacity to support reliable engine operation across varied driving conditions.

How does this filter affect engine performance?

A properly fitted air filter helps maintain the correct air-fuel ratio and prevents flow restriction that can reduce responsiveness. The Mann Filter C 28 004 delivers consistent airflow while capturing contaminants, which supports steady power delivery and throttle response under normal driving loads.

• OE-fit design reduces intake leaks and ensures correct sealing.
• Low flow resistance supports steady engine breathing and efficiency.
• High dirt separation prolongs time between maintenance intervals.
• Embossed pleats maintain shape under pressure and heat.

What makes the filter media different from standard filters?

The C 28 004 uses flame-retardant, water-resistant media treated with a protective coating to withstand humid or ash-prone environments. That treatment, combined with a high-efficiency fiber structure, captures fine particles without creating excessive backpressure.

• Special coating resists moisture and hot ash exposure.
• High dirt separation efficiency captures fine particulates.
• Low flow resistance minimizes impact on engine intake dynamics.
• Durable media construction extends filter life in real-world use.

Which Mercedes-Benz models is the C 28 004 compatible with?

This Mann Filter is intended for select Mercedes-Benz models where the C 28 004 specification matches the original equipment part. It replaces the factory air filter and fits vehicles that require this exact size and sealing profile.

• Compatible with select C-Class (C300, C350e) applications as specified by fitment guides.
• Fits applicable E-Class models (E300, E350) requiring this part number.
• Used in compatible GLC variants (GLC300, GLC350e) with matching filter housings.
• Also fits select SLC300 models where the C 28 004 is the recommended replacement.

How easy is installation and what should I check during replacement?

Installation follows the same basic steps as most panel-style engine air filters: remove the airbox cover, swap the element, and reseal the housing. Verify the seal and housing clips to prevent unfiltered air bypass after the new element is installed.

• Simple hand tools typically required; follow vehicle service manual steps.
• Ensure the filter seats squarely and the rubber seal contacts the housing.
• Inspect the airbox for debris and clean before fitting the new element.
• Confirm clip closure and absence of intake leaks after installation.

Who is this for? The Mann Filter C 28 004 is aimed at Mercedes-Benz owners and professional technicians seeking a direct-fit replacement in OE-quality for vehicles that specify this part number. It suits drivers who prioritize protecting the engine and intake components with a durable, moisture-resistant filter that maintains airflow and filtration efficiency across varied driving conditions. Whether you perform routine service at home or work in a shop, this filter provides a reliable, application-specific option to uphold engine performance and component protection.
