It's ironic that one of the most important . parts on your car is also one of the simplest: We're referring to your BMW Air Filter. Your air filter is the front line of defense against foreign material getting into that expensive engine. You'd be surprised at how much damage small particles can do, and how quickly. Your BMW air filter keeps those particles out, but it requires frequent maintenance to do that and still allow adequate airflow into the engine so you can make horsepower. After all, much like a vacuum cleaner bag, as the air filter gets dirty, its efficiency is reduced.

Make sure you follow your manufacturer's recommendations for air filter replacement. Most of the time, installing a new BMW air filter every year is the minimum replacement schedule, but if you drive in dusty conditions, or take frequent short trips, you should install a new BMW air filter more often. Better yet, add a high-flow aftermarket BMW air filter to your vehicle. You'll see improvements in power due to the increased airflow, and most high-flow air filters are also washable and reusable. That means you'll save money on air filter replacements down the line while you're enjoying better acceleration and passing power.
