K&N High-Flow Original Lifetime Engine Air Filter 33-2985 – Compatible with 2011-2016 Mercedes-Benz

Performance and protection for your Mercedes-Benz

The K&N High-Flow Original Lifetime Engine Air Filter is designed to help your Mercedes-Benz breathe easier. By delivering air more efficiently, it can increase airflow by up to 50%, a change that may contribute to crisper throttle response and smoother acceleration in daily driving. This is a proactive upgrade that focuses on air flow without compromising filtration.

Unlike disposable paper filters, this unit is washable and reusable. It fits directly into the factory air box, making installation quick and straightforward so you can get back on the road in minutes. The filter is backed by a robust 10-Year/Million Mile Limited Warranty, reflecting trust in its durability and long-term value. In addition, choosing a washable design helps reduce landfill waste compared with traditional disposable filters.

The media stack uses four layers of premium cotton gauze, treated with a specialized tacking agent to create a precise mesh. This combination aims to balance strong filtration with minimal flow restriction. Under normal highway driving, cleaning intervals are longer—roughly every 75,000 miles—depending on driving conditions, which can translate to fewer maintenance stops and more time on the road.

With the K&N 33-2985, you’re choosing a filtration solution intended to last, with the flexibility to maintain it at home and reduce waste over time. While results can vary by vehicle and driving style, many owners appreciate the balance of performance, durability, and environmental consideration.
