13717521037 BMW FILTER

This filter’s job is pretty simple, really. It cleans the air that comes into your engine. It catches dust, dirt, pollen, bugs – everything floating around out there – before it gets inside. It’s basically a barrier, protecting more sensitive parts. Think of your engine like lungs. It needs clean air to breathe and run right. The air filter sits right at the intake, so it’s the first line of defense. Air comes in, gets filtered, and then goes to the engine to mix with fuel for combustion. It's a pretty crucial part of how everything works. If your air filter gets clogged, it starts restricting airflow. That means your engine has to work harder to pull in air, which can lower your gas mileage and even reduce performance. You’ll notice if it’s really bad – maybe a loss of power when you accelerate, or the engine might even run a little rough. A clean air filter helps your engine last longer and run efficiently. You can find a replacement easily enough. Fixparts Online carries a good selection, but most auto parts stores will have what you need. Really, it's a fairly inexpensive maintenance item that can save you headaches down the road. Technical support included: Filter (MPN 13717521037) comes with a 12-month warranty!
