Manufactured of high quality aluminum alloy which expands and contracts at the same rate as the aluminum cylinder head. Selecting similar materials make for a more stable seal between
the two components.

The factory water manifold on most 24 valve, six cylinder vehicles is made of plastic. Unfortunately, plastic will not handle the heat or over-torquing of the mounting bolts. We have discovered that even the new plastic manifolds from BMW can be warped by as much as 1/16". Water leaks resulting from the failure of the original plastic component have claimed many engine failures. We have now reproduced this item in a more stable, low-pressure cast aluminum.
Regardless of the condition of the original unit on your vehicle, we strongly recommend replacing it to avoid future inconvenience. Inspecting the original piece may reveal a slight coolant stain. In this case, we recommend replacing the unit immediately. Replacement of seperate profile gasket required for installation.
Does not include Thermostat. Must be used with Thermostat Part #54445
