Prevent water ingress and protect your engine bay electronics with the Genuine CUPRA Water Box Seal 5FA823723. This OEM rubber seal fits between the water box cover (also called the plenum chamber cover) and the vehicle’s firewall/bulkhead, forming a watertight barrier to keep rain, debris, and moisture out of the cabin air intake and under-hood components.
Essential for maintaining proper drainage and sealing in the cowl area, especially during heavy rain or car washes.
