Audi 3.0T Gen 1 Thermostat Housing
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) that they want to use.

Superior Aluminum Housing
Our aluminum housing is designed to overcome two key flaws of the OEM plastic thermostat. The plastic tabs of the OEM thermostat are prone to breaking, causing the thermostat to fail closed, which can result in engine overheating and significant damage. Our 6061-T6 aluminum housing completely removes those tabs, significantly reducing the risk of thermostat failure. Additionally, aluminum can naturally withstand high temperature heat cycles for longer periods than plastic, making our thermostat more durable and reliable.
Optimized for Engine Performance
Our thermostat is designed to open at 85C, just like the OEM thermostat, ensuring optimal engine performance. For those seeking a "racing thermostat," our assembly seamlessly accommodates the Mishimoto racing thermostat.
Easy to Rebuild
Our product is 100% re-buildable, making it easy to replace lower temperature "racing" thermostats without sacrificing the benefits of the aluminum housing.
Cuts Maintenance Costs
Investing in our Audi 3.0T Thermostat saves you money on recurring maintenance costs. With our product, you won't need to replace a broken thermostat housing again.
3-Year Warranty
Due to our confidence in this product, we are happy to offer a 3-year warranty. This product has been 100% tested in-house on our own S4 with exceptional results.
What's in the kit?
This kit comes with a fully assembled aluminum thermostat housing which includes the housing, thermostat, O-rings, and a cross-over coolant pipe bolt.
Reviews
I found this part online when it just came out. It's a precision, quality, non-plastic replacement part, to replace an OEM item that has a reputation for cracking & failure. I contacted them immediately and was one of the 1st to receive one. It's a beautiful piece. Very well made and thought out. It's a permanent part because it should never fail. The only failure point is the t'stat itself, which is replaceable. Kudos to them for developing this. Hopefully they can do the same for the OEM PCV.
Super stoked with this product, very high quality piece of aluminum. Why would you replace your old plastic thermostat with another plastic thermostat only for it to fail again when you can spend the same money on an aluminum one that you never have to worry about again
Very well built! Owner went out of his way to get shipped early due to needing it for appointment at shop. 3k miles on it and no problems! Great alternative to oem plastic housing!
Works flawlessly and it's not one less thing to worry about on my 3.0t
