The Story Behind the Name
In German engineering, Luftstrom represents more than just air; it represents the perfect, laminar flow of an airstream. The factory throttle body is a bottleneck, a restriction that forces your engine to fight for every breath.
We developed the Luft-Strom to eliminate that resistance. By expanding the bore to a massive 84mm, we’ve transformed the intake from a narrow passage into a high-velocity corridor. When paired with our titanium intake, you aren't just cooling your charge; you’re feeding it. It’s the ultimate synergy of air and liquid, designed to let your Audi breathe, surge, and perform exactly as the engineers at Ingolstadt intended, only louder and much, much faster.

Luft-Strom Throttle Body FAQ
Do I need a wiring harness adapter?
Yes, the Luft-Strom uses a VDO-style connector, so you'll need a harness adapter. We offer our own plug-and-play harness to plug it into your factory harness.
Will this fit my stock intake?
You'll need the correct coupler for your intake's throttle body opening, and our Billet Throttle Body Adapter to mate it to the stock supercharger inlet.
Do I need a tune?
A larger throttle body changes airflow at the same throttle position, so we recommend having your tuner confirm your fueling and idle/drive-by-wire calibration after install.
A Word on Being Called a "Cheap Copy"
Every so often someone assumes that because the Luft-Strom costs less than a genuine VDO unit, it must be a knockoff, a copy, or a "you get what you pay for" gamble. It's none of those. The Luft-Strom isn't reverse-engineered off anyone else's part; it's our own 84mm design, manufactured in an ISO 9001 facility and backed by the same 2-year warranty we put behind everything we build.
We can sell it for less than the genuine OEM option because we're not paying OEM distribution margins or licensing fees, not because we skipped a step. If you want the badge, buy the genuine VDO unit we also carry. If you just want the bore, the warranty, and the lower price, that's what the Luft-Strom is for.
- Not a Clone: Our own design and tooling, not a copy of anyone else's part.
- ISO 9001 Manufactured: Built under a recognized quality standard.
- Real Warranty: 2 years, no fine print, no "as-is" disclaimer hiding behind the lower price.
Bottom line: a lower price than the OEM part isn't proof of a shortcut, it's proof that OEM pricing has margin built in that we didn't bother charging you.
