Better engine sound, engine cooling, and a weight savings of 10lbs.

Now in Colors! Black, Blue, & Red Filter Elements.

E chassis BMW owners have known for some time that removing their cowl and HVAC filter system not only reduces vehicle weight but also improves overall engine bay cooling, facilitates engine & DME box access for service, and lets the driver better hear how the engine is running. But there was always a catch. How to stop dirt and debris from falling into the interior ventilation system? Well BMS has finally come up with a solution. These cleanable lightweight dry filters look great while blocking dirt & debris from the cabin. Also known as the cowl delete. Water won't run into the HVAC system with or without the cowl filters as they are raised openings. Suddenly removing your cowl is not only for race cars.

Non-oiled dry filters. To clean rinse with water, let dry and reinstall. Do not oil. 

NOTE: There are different left and right cowl filters. Installing them on opposite/incorrect sides will visually deform the filter element. Please refer to the install guide for the correct install procedure.
