Overview
Upgrade your Audi 3.0T Gen 2 CREC engine with a 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, which is known to degrade, warp, and crack over time — leading to coolant leaks in the engine valley, low coolant warnings, and potential overheating.
Machined from aerospace-grade 6061-T6 aluminum and finished with a hard anodized coating for long-term corrosion resistance, this housing is precision-engineered and tested in the USA. It retains full compatibility with OEM and aftermarket thermostats and includes all necessary hardware and seals for a complete installation. Note: supercharger removal is required for installation. Compatible with CREC engine code only — not compatible with Gen 1 engines.

Frequently Asked Questions
Is this compatible with Gen 1 3.0T engines?
No. This thermostat housing is designed exclusively for the Gen 2 CREC engine code. It is not compatible with Gen 1 3.0T engines, which use a different housing design.
What vehicles does this fit?
This housing fits 2015–2018 Audi C7 A6, A7, A8, and Q7 models equipped with the 3.0T Gen 2 Supercharged TFSI engine (CREC engine code).
Does installation require supercharger removal?
Yes. Supercharger removal is required to access and replace the thermostat housing. This is an intermediate-to-advanced level installation and is the same access procedure required on the factory unit.
Will this work with my aftermarket thermostat?
Yes. The housing is compatible with both OEM and aftermarket thermostats, so it will work whether you are retaining the stock thermostat or upgrading to a performance unit.
What are the common symptoms of a failing factory thermostat housing?
Common symptoms include coolant leaks in the engine valley, low coolant level warnings, overheating or temperature fluctuations, a coolant smell from the engine bay, and visible cracks in the plastic housing.
