This machined thermostat replaces the factory plastic BMW M57/M47 housing that is renowned for leaking and breaking once you try pull the oem  joints apart.
 
Made using 6061 aluminium, this housing captures the OEM seal and fits the original 88 degree thermostat inside. 
The ports allow for rear cooling of the head via our adaption kit (coming soon!)
OR to even run any after market cooling systems (eg) gated turbos!
 
We recommend this for anyone who drags, tows or even for extra reliability on a daily. The thermostat housing also allows you to get rid of the plastic pipe work that is profound for breaking along the front side of the head. This also allows you to easily tap into the oil cooler system by routing the coolant line to the oil cooler plate.
