Vorsprung Autowerk Billet Throttle Body Upgrade Adapter (84mm VDO) , Audi 3.0 EA837 Supercharged
Unleash the Flow. Break the Gatekeeping.
Upgrade your Audi’s breathing capabilities without suffocating your wallet. The Vorsprung Autowerk Billet Throttle Body Adapter is engineered to seamlessly mate a massive 84mm VDO Throttle Body to your stock supercharger, delivering the airflow your build demands.
Engineered for Velocity, Not Just Fitment Most adapters on the market get one thing wrong: thickness. A thin adapter creates turbulence. We designed ours with the specific thickness required to create an optimized airflow path, maximizing velocity into the supercharger.
The All-In-One Solution Why drill into your manifold when you don't have to? We’ve integrated a dedicated Methanol (Meth) port directly into the adapter. Whether you are running WMI now or planning for it later, the port is there, ready to go.
End the "Audi Tax" We are tired of the gatekeeping that forces enthusiasts to buy overpriced, proprietary throttle body kits. With Vorsprung Autowerk, you have options.

Buy a brand new OEM VDO unit, now available direct from us.

Throttle Body Adapter FAQ
Do I need a wiring harness?
Yes, an 84mm VDO throttle body uses a different connector than your factory unit, so you'll need a harness adapter. We offer our own plug-and-play harness in addition to this adapter plate.
Is the methanol port required to use?
No, the integrated meth port is a convenience for WMI setups. If you're not running water/meth injection, it can simply be capped with the included 1/8" NPT plug.
Which throttle body should I use with this adapter?
It's designed to mate an 84mm VDO throttle body, such as our own Luft-Strom or our OEM VDO unit, to your stock EA837 supercharger.
A Word on Being Called a "Cheap Copy"
This adapter costs less than most of the proprietary throttle body kits it replaces, and every so often that gets read as "cheap must mean cheaply made." It's the opposite: we built this specifically because the market was charging Audi-Tax pricing for a piece of billet aluminum with a hole through it. Pricing it fairly isn't the same as cutting corners on it.
- Engineered, Not Copied: Our own thickness and port design, engineered for airflow, not reverse-engineered off someone else's part.
- Real Hardware Included: Metal gaskets, NPT plug, and every bolt you need, not a bare plate with extras sold separately.
- No Proprietary Kit Tax: You're not paying for a "kit" wrapper around parts that should be priced on their own.
Bottom line: a fair price on a well-made part isn't a red flag, it's just what happens when nobody's padding the margin.

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.

Can I install OEM parts myself, or is it better to have a professional handle it?
