BMW N54 N55 N52 Upgraded Coolant Flange

Mickey Mouse Coolant Flange for the BMW N52, N54 and N55 engines. Upgraded design.

Specifically designed for the cylinder head to thermostat hose on N5X known popularly as the "mickey mouse flange", this revised aluminum replacement addresses the common failure of OE style plastic flanges, includes sealing o-ring and hose clamp for complete installation.

The stock plastic flange included with the coolant hose which connects the thermostat to the cylinder head is extremely failure prone. This flange is known to break on it's own during normal vehicle operation. However, it's also known to break when replacing the hose assembly as a whole as regular maintenance.

Now you can replace the flange with a failure proof replacement.

It is highly recommended to replace this flange as preventative maintenance. There is no known mileage as to when the plastic flange will fail, failure is generally pretty random. Upgrade to this aluminum flange so that you don't risk potential issues.
