Audi 3.0T Billet Thermostat Housing, EA837 Gen 1 Non-Evo
Vorsprung Autowerk Billet Aluminum Thermostat Upgrade (3.0T)
Plastic has no place in your cooling system.
From the factory, the Audi 3.0T is a masterpiece of engineering except for one glaring flaw. Audi equipped this high-heat, high-performance engine with a cheap plastic thermostat housing. It’s not a matter of if it fails, but when.
After thousands of heat cycles and constant exposure to corrosive antifreeze, that factory plastic turns brittle. It cracks. It warps. And eventually, it dumps your coolant, leading to overheating and potential catastrophic engine failure.
The Permanent Solution: We don't believe in replacing a failed plastic part with another plastic part. The Vorsprung Autowerk Billet Thermostat is the bulletproof fix your supercharged engine deserves. Precision-machined from 6061-T6 aluminum, this unit is engineered to outlast the car itself. It eliminates the weak link in your cooling loop, giving you the reliability you need for daily driving and the durability you need for the track.
Engineered, Not Just Machined. We didn’t just make it metal; we made it smarter.
Ready to Drop In: Stop worrying about your temp gauge. This unit comes pre-assembled with an OEM-equivalent thermostat.
