A bad DISA valve can cause a variety of issues, from a loud racket in the engine bay, hesitation at low rpm and a rough idle with lean codes.

If the valve is making a loud noise, we recommend replacing it as soon as possible. It is possible for the pin holding the flap to be sucked into the motor causing serious damage.

Very easy to replace, just need to undo the 4 bolts holding it to the intake manifold.

Includes new mounting hardware

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:

E36 3 series: 323i 323is 323ic 325i 325is 325ic 328i 328is 328ic M3 1992-1998
E46 3 series: 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi M3 1999-2005
E39 5 series : 525i 528i 530i 1997-2003
E85 X3 : X3 2.5i X3 3.0i 2004-2006
Z3 : Z3 2.3 2.5 2.8 3.0 1997-2002
E85 Z4 : Z4 2.5i Z4 3.0i M54 engine 2004-2006

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.

This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. 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.

Fits the following BMWs:
