GPS Audi EA837 3.0T Billet Thermostat Housing (Gen 1)

Replaces 06E121111AL - OEM Audi 3.0T Thermostat VERSION 2 IS HERE: We made 2 big changes to farther improve the CNC Machined Housing. The first big change was to correct the overcooling issue that some customers (particularly in colder climates) were experiencing. If you purchase one of the original version 1 thermostat housings, please reach out to me and i will ship you a retrofit kit free of charge. The second big change was moving the assembly screws to the outside of the oring grove. That thoroughly ensures the screw cannot drop into the engine block if it were to ever come lose.    The GPS billet aluminum Audi 3.0T Thermostat housing is a game-changer in engine performance and reliability. Say goodbye to the dreaded plastic thermostat housing and hello to a more dependable ride with our CNC machined, aluminum anodized thermostat.   Two Options include: 1: Thermostat Housing Only. This option is for those who already have a thermostat (like the mishimoto racing thermostat) tha
