Is your Mercedes-Benz C230 (2003-2005 W203 model with the 1.8L 4-cylinder engine) running rough, stalling, or just not feeling right? A faulty Mass Air Flow (MAF) sensor could be the culprit. This A-Premium replacement is designed to get your ride back to smooth performance. This sensor is a critical piece—it measures the amount and density of air entering your engine so the computer (ECU) can calculate the perfect fuel mixture. When it fails, you get poor fuel economy, hesitation, and maybe even a check engine light. This one's a direct fit with 5 blade terminals and two mounting holes for a bolt-on install. It's made from tough PBT material with 40% fiberglass reinforcement, and it comes in black. The part numbers it replaces include MAS0284, 2710940248, A2710940248, 8ET009142-351, 707759180, and 5WK9638Z. Before you order, double-check your vehicle details using the fitment tool at the top of the page! We're so confident in this part that it comes with a one-year unlimited-mileage guarantee. Don't let a bad sensor ruin your drive. Installing a fresh, high-quality MAF can clear up those intermittent faults, restore proper engine running, and even help extend the life of other components. Get back on the road with confidence and peace of mind.
