Lackluster performance from a high-performance machine can only mean one thing: poor maintenance. Keep your car at peak operating levels by doing simple things like replacing your air filter. Stock BMW air filters are made from pleated paper. In some cases you can simply remove it from the car and give it a good shake or brush with a very soft bristle brush. But for heavily soiled filters a replacement is the only option. A lot of fresh air is crucial for your BMW's engine to make power. Don't let the filter be the weak link. We only offer OEM quality brands for air filters.
