Fitment Notes

Direct drop-in replacement for the factory engine air filter - installs in the existing OEM airbox with no modifications required.
Dual airbox applications: Some larger-displacement Mercedes-Benz V8 and V12 engines (including certain S-Class, SL-Class, and AMG models) use two separate airboxes - one per cylinder bank. These applications require two filters (two units of PN 28-20181) for a complete service. Verify whether your specific engine uses a single or dual airbox arrangement before ordering.
AEM's own product title covers 1998-2010; JEGS extends confirmed fitment to 2014. Multiple dealers list 1999-2015 coverage. Always confirm your specific year and model against AEM's vehicle fitment lookup to verify applicability for model years beyond 2010.
This filter will not void your Mercedes-Benz factory vehicle warranty.
Sold individually - one filter per package.

Features

AEM DryFlow Oil-Free Synthetic Media - Up to 99% Filtration Efficiency: The 28-20181 uses AEM's DryFlow non-woven synthetic filter media to deliver high airflow and up to 99% contaminant capture efficiency without requiring filter oil. Unlike oiled cotton-gauze performance filters, DryFlow eliminates the risk of MAF sensor contamination from oil overspray - important on Mercedes-Benz engines that use sensitive hot-wire mass airflow sensors. The synthetic media does not degrade from repeated cleaning cycles the way cotton gauze can.
Increased Horsepower and Throttle Response: AEM's lower-restriction synthetic media allows more air volume into the M112, M272, M276, M113, and M156/M157 engine families compared to the factory paper element - improving throttle response and supporting power gains across the RPM range on both naturally aspirated and AMG-tuned applications.
Washable and Reusable - Lifetime Filter: Clean with AEM filter cleaner (PN 1-1000), rinse with water, air dry completely, and reinstall - no oiling required. Designed to last the lifetime of the vehicle.
Large-Format Panel - 13.875 in x 5.219 in: The large 13.875 x 5.219-inch panel dimensions provide substantial filter media surface area for the high airflow demands of Mercedes-Benz 6-cylinder and V8 engines across this broad model family.
Outstanding Performance in Dusty Conditions: DryFlow synthetic media maintains both airflow and filtration efficiency in dusty environments - performing consistently even in demanding driving conditions.
Direct Drop-In Fit: Engineered as a direct dimensional replacement for the OEM paper element in the factory Mercedes-Benz airbox - no modifications, adapters, or additional hardware required.
Will Not Void Mercedes-Benz Factory Warranty: Compliant with the Magnuson-Moss Warranty Act; the 28-20181 will not void the manufacturer's vehicle warranty when used as directed.
Made in the USA: Manufactured by AEM Induction Systems to precision quality standards.

Product Description

The AEM 28-20181 is a DryFlow synthetic drop-in panel air filter for 1998-2014 Mercedes-Benz C, CLK, E, GL, ML, R, S, and SL-Class models equipped with 6-cylinder and V8 gasoline engines - one of the broadest Mercedes-Benz application filters in AEM's lineup. The large 13.875 x 5.219-inch panel fits directly into the factory Mercedes-Benz airbox as a dimensional replacement for the OEM paper element, with no modifications required.

AEM DryFlow oil-free synthetic media delivers up to 99% filtration efficiency without requiring filter oil - eliminating the MAF sensor contamination risk that oiled performance filters present on Mercedes-Benz hot-wire MAF-equipped engines. Washable with AEM filter cleaner and reusable for the lifetime of the vehicle. Will not void Mercedes-Benz factory vehicle warranty. Made in the USA. Lifetime Limited Warranty.

Important: Some larger-displacement Mercedes-Benz V8 and AMG engines use dual airbox configurations with one filter per cylinder bank - these applications require two units (2x PN 28-20181) for a complete replacement. Verify your specific engine's airbox arrangement before ordering.
