Air Intake 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!

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

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:

E36 3 series: 318i 318is 318ic 318ti 1992-1998
Z3 : Z3 1.9

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.

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.

The flexible sealing surface of these filters adapts to varying filter housing shapes, ensuring a perfect fit and sealing surface without the need for gaskets or sealants. This design also ensures the filter always returns to its original form.

Featuring three layers of oil-free synthetic media, these filters require no oil during maintenance, providing maximum convenience. The progressive layering of the media offers excellent filtration efficiency and dust-holding capacity, making them ideal for street use.
