Upgraded 80mm throttle body for your supercharged EA837 3.0T 


Our throttle body upgrade mounts in the factory location, removing any need to purchase a proprietary intake. Any 3.5" intake you already have on your car will be a direct fit for this throttle body upgrade, or you can choose to upgrade to our Omega 4" intake kit for maximum flow!

Our billet throttle body adapters feature a smooth taper and are milled to perfectly match the OEM 70mm supercharger inlet. We have engineered these plates to be able to be easily ported up to 80mm to match even the most aggressively ported superchargers, something you simply can't do with other upgraded TB kits due to their snout-style design.

The adapter plates also have a meth bung machined into the top face for easy WMI installation just after the throttle body, eliminating the need to drill your intake or supercharger inlet. WMI bungs will come pre-plugged with a stainless 1/8" NPT plug.


  • 80mm throttle body provides huge flow, even when matched to the largest 80mm ported superchargers
  • Pre-tapped for WMI, just add meth!
  • Billet reducer is easily port-matched to any supercharger inlet size
  • Compatible with any upgraded TB ECU software you may have such as Jackal, APR, 034 
  • Stock-location mounting means compatibility with your existing intake, no intake purchase is necessary to run our kit
  • 31% increase in cross-sectional area compared to the stock throttle body
  • 100% compatible with the MercRacing MRA1900 supercharger upgrade!


  • 80mm throttle body
  • Billet reducer/adapter plate to mount to your supercharger
  • 1/8" NPT meth port with stainless plug
  • All required hardware & gaskets

This kit will ship with a 3.5" coupler included. If you require a different coupler, please include it in the notes. If you order the throttle body with our 102mm Omega kit, a 3.5" to 4" reducer will be included.

Stock throttle body = 3.00" coupler size
GAS 80mm throttle body = 3.50" coupler size
Omega Intake Kit = 4.00" coupler size
