This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox.

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.

Fits the Following BMWs:

E82 E88 135i N55
E90 E92 E93 335i 335xi N55

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!

• Covered by the K&N Million Mile Limited Warranty
• Washable and reusable
• Emissions legal in all 50 states
• Will not void vehicle warranty

aFe POWER performance air filters utilize a rounded, evenly spaced pleat design that maximizes the usable filter surface area, resulting in increased airflow and greater dust retention capacity. The pliable sealing surface of these filters conforms seamlessly to varying filter housing shapes, ensuring a perfect fit and sealing surface without the need for additional gaskets or sealants.

Constructed with a durable 360-degree polyurethane frame, aFe POWER flat panel performance air filters maintain their original molded shape even after multiple heat cycles in the engine bay, unlike other materials that may degrade over time.

Featuring five layers of pre-oiled cotton gauze media, these filters deliver maximum performance with their progressive layering that allows consistent airflow even when dirty. Ideal for both street and track use, these Pro 5R filters can be easily rejuvenated with aFe's POWER CLEANER and blue air filter oil.
