VDO OEM 84mm Throttle Body Upgrade, Audi 3.0T EA837 Supercharged

Skip the Junkyard Roulette

Sourcing a genuine 84mm VDO throttle body for a 3.0T upgrade used to mean digging through junkyard listings, gambling on a stranger's used part off eBay, or paying a dealer parts counter's idea of a fair price. We got tired of watching people roll the dice, so we started stocking the real thing ourselves.

The VDO OEM 84mm Throttle Body (part number 13547535308) is the same genuine unit the Audi 3.0T EA837 tuning community has been chasing for years. It started life as an electronic throttle body on BMW's N62 4.8L V8 (550i, 650i, 750i, 750Li, and X5, 2006-2010) before the tuning world discovered its bore made it the ticket to real airflow on a supercharged 3.0T. Now it's sitting on our shelf instead of someone else's parts bin.

What You're Actually Getting

This is a genuine VDO unit, not a reproduction and not a knockoff wearing a similar part number. It's a fully electronic, drive-by-wire throttle body with throttle position sensing built into the housing, aluminum construction, and the fit and finish you'd expect from a real OEM part.

Heads up on what else you'll need: this throttle body uses a different electrical connector than your factory 3.0T unit and a different mounting bore than your stock supercharger snout, so it will not bolt on by itself.

• ✅ Billet Throttle Body Adapter - mates this 84mm bore to your stock or ported supercharger opening
• ✅ Vorsprung Autowerk Throttle Body Harness - repins the VDO connector to plug into your 3.0T wiring
• ✅ Tuning support - your ECU needs to know a bigger throttle body is there to actually use it

Bottom line: this is the genuine core component of the 84mm throttle body upgrade. Pair it with our adapter and harness and you have the complete kit, without the junkyard gamble.

Note: this throttle body requires the billet adapter and wiring harness, sold separately, to fit the Audi 3.0T EA837 platform. It does not bolt directly to your factory supercharger or wiring harness on its own.

Frequently Asked Questions

Is this a direct plug-and-play replacement for my stock throttle body? No. You will need our billet adapter plate to mate the bore to your supercharger and our harness to convert the connector.

Is this a genuine VDO part, or a clone? Genuine. This is the authentic OEM VDO unit, part number 13547535308, not a reproduction.

Do I need a tune after installing this? We recommend it. A larger throttle body changes your airflow, and a proper tune is how you actually capture the gains instead of just having a bigger part bolted on.

Will this work with a ported supercharger? Yes, provided you pair it with the ported-opening version of our billet adapter.
