Fitment Notes

• Replaces OEM Mercedes-Benz air filter part numbers 276 094 00 04 and A276 094 00 04, also cross-referenced as WIX 49034 and FRAM CA11439.
• Fits vehicles equipped with the Mercedes-Benz M276 DE35 naturally aspirated V6-3.5L engine with direct injection (BlueEFFICIENCY designation). Does NOT fit turbocharged M276 variants (e.g., E400 hybrid, V6-3.0L bi-turbo applications).
• The C300 fitment applies only to the 2013-2014 model years (W204 chassis with M276 V6-3.5L). The 2008-2012 C300 used the earlier M272 V6-3.0L and requires a different filter.
• The GLE350 fitment covers 2016-2019 (W166 platform, carryover from ML350). The 2020+ GLE350 uses a completely different chassis and airbox and does NOT fit this filter.
• Includes a coupler - a component designed to ensure a proper, secure seal within the Mercedes factory airbox housing.
• This is a direct OE drop-in panel replacement for the factory airbox - no modifications required.
• Verify your specific chassis code and engine designation before ordering, as Mercedes-Benz uses multiple engine variants across the same model designations in overlapping years.

Features

• Pro DRY S Filter Media: Three layers of progressively finer oil-free synthetic media deliver improved filtration without oiling, eliminating any risk of MAF sensor contamination on Mercedes M276 direct-injection applications.
• Built-In Reinforced Metal Frame: An internal metal reinforcement structure provides additional rigidity beyond the standard polyurethane frame - a premium construction feature unique to this application to ensure long-term filter integrity under boost pressure cycles in the factory airbox.
• Deep 20mm Pleats / 42-Pleat Count: Deeper-than-standard pleats and a higher pleat count provide significantly increased usable filter surface area for greater airflow and dust-holding capacity compared to the OEM paper element.
• Coupler Included: Comes with a coupler that ensures a secure, rattle-free seal within the factory Mercedes airbox - no additional hardware or sourcing required.
• Oil-Free Design: No oil required for cleaning or reinstallation - eliminate the recurring cost and mess of oiled filter maintenance, and prevent MAF sensor exposure to oil residue.
• Outflows the OEM Paper Element: Higher airflow through the factory housing supports improved throttle response and engine breathing from the M276 V6-3.5L.
• Progressive Bump Seal: Pliable urethane sealing surface conforms precisely to the factory Mercedes airbox housing for a tight, gasket-free, leak-proof fit that returns to its original form after every service.
• Full 360-Degree Urethane Housing: 100% polyurethane construction on all four sides provides OE-style panel fit, long-term structural durability, and resistance to engine bay heat cycles.
• Washable and Reusable: Clean with aFe POWER Cleaner, rinse, dry, and reinstall - no re-oiling required, making service intervals simple and cost-effective for European vehicle owners.
• Does Not Require a CARB EO#: 50-state legal - no emissions compliance concerns.
• Limited Lifetime Warranty: Backed by aFe POWER's limited lifetime warranty under normal use and proper maintenance conditions.

Product Description

The aFe POWER 31-10250 Magnum FLOW Pro DRY S Air Filter is a direct OE drop-in panel replacement engineered for the Mercedes-Benz M276 DE35 V6-3.5L engine, covering a wide range of W-class models from model years 2012 through 2019. Compatible vehicles include the C300 (2013-2014), C350 (2012-2015), E350 (2012-2016), E400 (2013-2015), GLK350 (2013-2015), ML350 (2012-2015), GLE350 (2016-2019), R350 (2012-2013), and SLK350 (2012-2016) - all sharing the same factory airbox and OEM filter (Mercedes-Benz part# 276 094 00 04). What sets the 31-10250 apart from standard aFe OE replacements is its enhanced construction: a built-in reinforced metal frame adds structural rigidity beyond the standard urethane housing, 20mm deep pleats with a 42-pleat count maximize usable filter surface area, and a coupler is included to ensure a secure factory fit. Three layers of progressive oil-free Pro DRY S synthetic media outflow the OEM paper element while maintaining excellent filtration efficiency for everyday street use.

The oil-free Pro DRY S media is especially well-suited to the M276 direct-injection V6, where oil-based filters can pose a risk to sensitive mass airflow sensors. Because no re-oiling is required after cleaning - simply use aFe POWER Cleaner, rinse, air dry, and reinstall - service intervals are simplified and MAF contamination risk is completely eliminated. Installation is a direct drop-in to the factory airbox with no modifications required. The included coupler ensures a precise, rattle-free seal, and the integrated urethane bump seal conforms to the housing for a secure, leak-proof fit every time.

For Mercedes-Benz owners managing the M276 platform across multiple body styles and model designations, the 31-10250 replaces the cost of recurring OEM paper filter replacements with a single lifetime investment. It is 50-state legal, requires no CARB EO#, and is backed by aFe POWER's limited lifetime warranty. Buyers should confirm their specific chassis code and engine designation before ordering - the C300 fitment is limited to 2013-2014 (M276), the GLE350 applies only to the 2016-2019 W166 generation, and turbocharged M276 variants are not compatible with this filter.
