UPDATE: We are expecting our latest shipment of harnesses to arrive mid-December 2021. Upon arrival, orders will be fulfilled in the order they were received. Thank you for your patience!
Due to an overwhelming demand for these kits, please allow 2-3 weeks minimum for order fulfillment. This is due to limited availability from the manufacturer, NOT because of a lack of fulfillment from Garage Auto Sports. We appreciate your understanding while iAbed Industries works to ramp up production and availability.
Please specify the size of your intake in the order notes and will include a reducing coupler at no charge. If you are ordering a throttle body kit with our GAS Titanium Supercharger Inlet Pipe, or if you don't need a coupler, specify "no coupler". If no coupler is specified, one will not be included with your order.
Stock throttle body = 3.00" coupler size
75mm throttle body = 3.25" coupler size
82mm throttle body = 3.50" coupler size
Experience increased horsepower, torque, and throttle response with the iABED throttle body upgrade kit for the Audi 3.0T Supercharged engines. These kits are plug and play, but to experience the maximum benefits, pair it up with a tune that takes full advantage of that increased cross-sectional area!
Note that the 82mm throttle body will require tuning due to the immense increase of cross-sectional area (~40%). Fault codes P0068 and P2279 will result if the car is not tuned specifically for the larger TB. All of our tuning stages (1-3) offer an option for both the 75mm and 82mm throttle bodies!

Machined from T6061 billet aluminum, the adapter plate is profiled to allow a smooth transition from the OEM port opening of 70mm to the opening of the throttle body at 75mm. All adapter plates come standard with a 1/8” NPT tap for water/methanol injection and a plug should you not have methanol injection. Choosing a Bosch throttle body as a basis for our product allowed us to work with a more compact in size throttle body. This meant that getting a throttle body behind the cylinder head and bolted to the supercharger inlet did not require a cast adapter (expensive to machine an offset adapter) making our adapter more affordable to manufacture which means the end-user/customer gets a financially appealing solution.
We use a Porsche 997 Throttle Body (Manufactured by Bosch in Germany). The OEM Part Number used is 997 605 115 01 (BOSCH #: 0 280 750 474).
Our throttle bodies come with a limited lifetime warranty to the original purchaser (good luck getting that from any other vendor on an electrical component).
Our adapter harness is the culmination of 2 years+ worth of R&D. We have a specialty designed circuit board that allows the conversion from Siemens/VDO/Continental 11Kohm to Bosch 1Kohm making this plug and play for all applications. The circuit board is enclosed in a T6061 CNC’ed billet housing and epoxied to ensure functionality under all weather conditions (no water is getting into this thing). The pigtails are OEM Porsche for the throttle body and OEM Volkswagen /Audi for the harness side. We only use OEM pins in our harness construction to ensure the operation is the same as OEM.
Finally, the harness is wrapped with electrical wrap and covered in aerospace-grade fire retardant wrap.
This harness also allows similar-sized 70mm DBW throttle bodies from the B5 S4 or Porsche 986 to work on the 2.0 TFSI Turbo motors.
When asked why we didn’t use the Dodge Hemi 5.7L / 6.1L Throttle Body in our kit, the answer was simple:
Like all of our products, we advocate for the use of certain brands. Similar to Fluidampr for Crankshaft dampers, Mahle Motorsport for pistons, ARP for hardware, we believe that Bosch (Bosch Motorsport) offers the absolute best drive-by-wire (DBW) throttle body on the marketplace. The construction of Bosch units vs competing Siemens/VDO/Continental units is superior and they are more compact due to the family sharing of components such as TPS covers and drive motors.
We have been in the drive-by-wire throttle body game since 2004. It is no secret that the Dodge Hemi unit is the affordable “go-to” throttle body by most aftermarket companies because they are cheap, and manufactured by Siemens/VDO in Germany.
However, we don’t use VDO/Siemens units for a few reasons:
- Construction (as mentioned above) - unlike Bosch, Siemens/VDO throttle bodies are manufactured as affordable as possible. Reinforced Plastic is used for throttle plates where aluminum should be used. In high horsepower 2.0T applications, the throttle plates snap into 2 pieces which may cause catastrophic engine failure should they go unnoticed. Bosch throttle bodies will never fail in this manner.
- Water/Methanol injection – Bosch units have seals between the throttle shaft and the housings so if you are spraying meth pre-throttle body, the likelihood of the meth crystallizing on your circuit board is slim to none. This is a major reason most VDO units fail in a water/meth setting.
- Ability to rebuild: Siemens/VDO units are not serviceable, whereas Bosch units are. Unlike other companies, we offer a limited lifetime warranty on our products!
The wiring harness is the base option of this kit and thus will automatically come with every order.
Adapter Plate w/ Gaskets and Hardware
You will need this in order to mount the larger throttle body to the OEM location on the blower. Most people will need this option.
Include Throttle Body
Please select which throttle body you would like to add to your order.
Include Silicone Transition Coupler
If you need to connect the larger throttle body to an existing CF or Aluminum intake, you may need to include a silicone coupler. See our size chart above for details.
