Billet Aluminum Thermostat Housing for Audi 3.0T Gen 2 CREC - Precision CNC-Machined Upgrade
Upgrade your Audi 3.0T Gen 2 CREC engine with our precision CNC-machined billet aluminum thermostat housing. Designed specifically for 2015-2018 C7 A6, A7, A8, and Q7 models, this direct replacement eliminates the common failure point of the factory plastic thermostat housing.
Why Upgrade from Factory Plastic?
The factory Gen 2 CREC thermostat housing suffers from the same issues as Gen 1 - plastic degradation, warping, and cracking over time. These failures lead to coolant leaks in the engine valley, low coolant warnings, and potential overheating. Our billet aluminum design eliminates this failure point with aerospace-grade 6061-T6 aluminum construction and hard anodized finish.
Common symptoms of failing thermostat housing:
Coolant leaks in engine valley
Low coolant level warnings
Overheating or temperature fluctuations
Visible cracks in plastic housing
Coolant smell from engine bay
Features:
CNC-machined from solid 6061-T6 billet aluminum
Anodized finish for corrosion resistance
Gen 2 CREC-specific fitment
Direct bolt-on replacement for OEM plastic housing
Precision-engineered and tested in the USA
Eliminates plastic failure point

Installation Note: Requires supercharger removal for installation. Not compatible with Gen 1 engines - CREC only.
Thermostat/housing was replaced on my car at 84k km, went to change this in as preventative maintenance at 150k, and it turns out the plastic housing was leaking already!!! This gives so much needed peace of mind.
