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