Audi 3.0T Gen 1 Thermostat Housing

Replaces OEM Part Number 06E121111AL – Audi 3.0T Thermostat

VERSION 2 NOW AVAILABLE
We've made two major upgrades to further refine our CNC-machined thermostat housing:

1. Resolved Overcooling in Cold Climates – Version 2 addresses the overcooling issue reported by some customers, particularly in colder environments. If you purchased a Version 1 unit, contact us and we’ll send you a free retrofit kit.

2. Improved Screw Placement – Assembly screws have been repositioned outside the O-ring groove to eliminate the risk of hardware falling into the engine block in the rare event of loosening.

The GPS Billet Aluminum Thermostat Housing is a significant upgrade over the factory plastic version, delivering enhanced durability, reliability, and performance. Anodized and CNC-machined for precision, this housing is designed to last.

Available in Two Options:

• Thermostat Housing Only
  Ideal for those using their own thermostat insert (e.g., Mishimoto Racing Thermostat). Click HERE for the Thermostat Housing Only install video. 

• Complete Thermostat Assembly
  Fully pre-assembled and drop-in ready for a hassle-free install.
