Universal High-Flow Air Filter
Give your engine the airflow it deserves with this reusable, high-performance air filter—perfect as a direct replacement for an ECS intake system or as the finishing touch for your custom intake project.
Dimensions: 4.5" Base OD • 6" Filter Height • 3.5" Top OD
Upgrade from your restrictive factory filter to an ECS Tuning High-Flow Dry Air Filter and let your engine breathe freely. Improved intake flow enhances power throughout the rev range while helping maintain efficient fuel economy.
Oiled vs. Dry Filters — Which Is Right for You?
Oiled Filters
Offer slightly higher airflow for maximum performance
Require more frequent cleaning
Must be re-oiled after each cleaning
Long-term reusable design saves money over disposable paper filters
Dry Filters
Provide excellent airflow with minimal maintenance
Easily cleaned with warm, soapy water—no oiling required
Still flow significantly better than OE paper filters
Fully reusable and cost-effective
Both versions deliver superior performance over stock filters while offering the long-term benefit of reusability. Choose the option that best fits your maintenance style and performance goals.
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!

Since 1999, aFe (Advanced FLOW Engineering) has been developing and manufacturing high quality accessories in their facility in Corona, California. Starting with air filters and intake systems, and now expanding into exhaust systems, suspension components, tuning modules, and more, aFe products are a great way to improve the performance of your BMW without altering its fundamental character. Owned by a BMW enthusiast, aFe power is recognized the world over as a leader in quality performance products for your BMW.
This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:
E31 8 series: 840i 840ci 1991-1999
E32 7 series: 740i 740il 1993-1994
E34 5 series : 530i 530i Wagon 540i 1993-1995
E34: M5 1991-1993
E39: M5 2000-2003
E53 X5 : X5 4.4i 4.6is 4.8is
Z8 : Z8
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.
