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.
Check the Intake category for Performance Air Intakes & Drop In Performance Air Filters
K&N's drop-in air intake filter is constructed from cotton gauze material between aluminum mesh - this makes for a long lasting, high performance drop-in intake filter. These are very easy to remove and maintain. Turner Motorsport recommends this as one of the first maintenance/modifications you make to your vehicle after you purchase!
K&N's drop in air filters allow increased airflow - dirt and particles stick to the oil on these filters, making them more effective than traditional paper filters in terms of protection. Additionally, K&N believes their filters are more efficient than paper filers - this means more oxygen getting into the engine, allowing vaporized fuel to burn more efficiently and increasing horsepower and fuel economy. The best of both worlds!

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.
