Are you swapping your om648 into a pre-emission vehicle and trying to tidy up the intake system? Swap out the factory mixing chamber for a simple 3" adapter. Our adapter comes with a 1/8"-27 port that will accept most aftermarket pressure sensors. Clean up that engine bay and make things much simpler!
This is NOT recommended for factory cars do to emissions regulations and possible tuning requirements.
Due to limited availability, intake gasket 6130980180. The hardware not included (3 factory bolts can be reused).
