ECS Tuning Metal Thermostat Housing for 1.8T 20v

Upgrade your thermostat housing from the brittle plastic piece, used from the factory, to an ECS Tuning Heavy Duty Cast Aluminium!

In house designed by ECS Tuning's team of engineers, we specified our housing to be different than anything else available. A worthy Heavy Duty / Upgrade solution, we started with a specific cast alloy to handle the stress and abuse that an engine's cooling system is constantly subjected to. You can count on the dependability of this ECS housing. 

Other features include a larger bore diameter for increased flow and post machined sealing surfaces at the mounting flange and coolant hose fitting for optimum sealing capabilities. A machined hose barb is designed into this part to match the OEM profile while keeping the coolant hose properly secured from blowing off as cooling pressure rises. 

PLEASE NOTE:
- Hardware, O-ring seal and replacement thermostat are not included
