4G63 Thermo
Housing BlockOff


This product is for those of you who want to switch over to an electric water pump setup, and don’t need all of the clutter of the stock thermostat housing any more. The -16ORB port makes it easy to adapt to any type plumbing that you may be running. On DSM’s, you will have to add some sort of coolant expansion reservoir to act as a fill point, but if you’re at the point of adding an electric water pump, this shouldn’t be a big deal. These pair nicely with our water pump blockoffs for a complete setup.

  • Machined 6061 Aluminum Construction
  • -16AN ORB Port
  • Works on all 4G63’s (DSMs, Evo 1-9)
