Our billet t-stat housings are available in two sizes, one for the 144/170/200ci engines, and one for the 250ci engines. Both styles come with a 3/8" hole, which is used for a temperature sending unit, however the 250ci housing can be ordered without. (see options). Gasket included.  

They are available in a natural finish (can be painted or powder coated), anodized (red, blue, black, or gold), or fully polished. The 250ci housing, without the hole, is shown below. The 144/170/200ci versions are slightly smaller to clear the water pump pulley.

NOTE: The red, blue, and gold anodized units are limited (until supplies last) as we will no longer offer these colors once they are gone.
