BMW Air Filters

When changing over to the Euro air box, you want to ensure you are still getting the best air flow possible through the filter. This K&N filter is our best recommendation for increased flow and power!

K&N's 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

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!

This filter fits the LEFT SIDE intake airbox on all E60 M5 and E63 M6 (and E64 M6 convertible). Be sure to also get the right side filter, part# 33-2350.

Stock air filters are not designed for getting the highest flow rate possible. This causes air flow restrictions that prevent the highest possible power from the stock design. With COBB's BMW N54 High Flow Air Filter, designed to directly replace the stock air filter ( BMW Part # 13717556961), you can expect the highest flow rates from a stock style design while still maintaining maximum filtration.

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
