Product Description

The K&N 33-2405 is a high-flow, washable drop-in panel air filter built specifically for Mercedes-Benz AMG models equipped with the naturally aspirated M156 6.2L V8 engine, covering applications across the C63, CLK63, CLS63, E63, ML63, CL63, R63, S63, and SL63 AMG from 2006 through 2015. The M156's dual-airbox layout requires one filter per bank, so two units are needed per vehicle. Constructed with multiple layers of precision-oiled cotton gauze between aluminum wire mesh screens, the 33-2405 flows significantly more air than the restrictive OEM paper filter while maintaining up to 99% filtration efficiency - delivering improved throttle response and incremental horsepower gains on an already potent naturally aspirated V8.

Installation is straightforward - remove the stock filters and drop the K&N units directly into the factory airboxes. No adapters, tools, or modifications are required. With a service interval of once every 75,000 miles and K&N's 10-Year/Million Mile Warranty, the 33-2405 is a low-maintenance, long-term performance upgrade for M156-powered AMG owners who want maximum airflow without sacrificing OEM fitment or engine protection.
