Description
Magnuson Air Inlet Adapter 112/120mm to 90/103mm
The Magnuson air inlet adapter allows compatible TVS2650 supercharger systems with larger inlet adapters to use smaller 90–103mm throttle bodies with the stock bolt pattern. This billet adapter provides an excellent solution if you want to run your current throttle body now while keeping the option to upgrade later.
When you’re ready to move to a Nick Williams 112mm or 120mm throttle body, simply remove the adapter and install the larger throttle body onto the compatible inlet.
