Product Description

The K&N 33-3142 is a direct-fit high-flow replacement air filter engineered for the Mercedes-Benz M264 turbocharged four-cylinder engine platform, spanning the W205 C-Class, W213 E-Class, X253 GLC-Class, and V167 GLE-Class. Its layered, oiled cotton gauze construction flows significantly more air than the restrictive stock paper element, delivering sharper throttle response and improved combustion efficiency across this wide range of luxury vehicles. The filter drops directly into the factory airbox without modification, making it a five-minute upgrade.

Unlike disposable OEM paper filters that require replacement at regular service intervals, the K&N 33-3142 is washable and re-oilable every 50,000 miles, making it a long-term cost-saving investment for Mercedes-Benz owners. It works seamlessly with all factory electronics including the MAF sensor and will not trigger warning lights or affect vehicle warranty status. Backed by K&N's 10-Year / 1,000,000-Mile Limited Warranty and confirmed emissions-legal in all 50 U.S. states.
