The BMW Firewall Cowl / Water Deflector Cover, OEM 8402642, is a genuine used part removed from a donor vehicle. Also known as a water deflector cover, it seals the cowl area at the base of the windshield on BMW X5 models, channeling rain and road spray away from the cabin air intake and engine bay. A cracked or missing cowl often causes water intrusion onto the cabin filter or electronics, leading to musty odors or electrical faults.
