Product Description

The K&N 33-2256 is a washable, reusable drop-in replacement air filter for the Mercedes-Benz AMG supercharged M112 platform - covering the C32 AMG, SLK32 AMG, and the Chrysler Crossfire / Crossfire SRT-6, which shares the R170 SLK platform and its AMG-developed supercharged 3.2L V6. All vehicles in this fitment group use a dual-airbox configuration requiring two filters per vehicle; each filter drops directly into one side of the split factory airbox without modification and is fully compatible with OEM MAF sensors. This listing is sold as a single filter - order two to complete the installation.

Only needing cleaning every 75,000 miles, the K&N 33-2256 is a practical long-term upgrade for owners of these rare supercharged AMG models and the Chrysler-badged Crossfire. Whether fitted to a C32 AMG sedan or a Crossfire SRT-6 coupe, this filter delivers improved airflow and throttle response from the hand-built M112K engine without voiding the factory warranty.
