4G63 Thermostat Housing Delete

Sensor Ports

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.

Also available with sensor ports which adds one 3/8"NPT and one 1/8"NPT port to the side for use with temp sensors.

  • Machined 6061 Aluminum Construction
  • -16AN ORB Port
  • Works on all 4G63’s (DSMs, Evo 1-9)
  • (On sensor port version) One 3/8"NPT and One 1/8"NPT Port

Please note... If product is not listed as in stock, there may be a lead time of up to 8 weeks. Please contact via email with any questions regarding lead times on specific products. As we are a small operation, it is tough to keep everything in stock, and we typically only run a batch of something if there are a few backorders placed. With that being, said, we do try our best to run extras, and intend to stock everything as soon as capacity allows. Thanks for everyone's understanding and patience!
