Goodmorning,
I while ago i purchased an Integrated Engineering manifold for my S3.
I still have to get it fitted, but i first have a question that need to get out of the way.
With this manifold installed, the runner flaps in the intake pipes will no longer be there.
But in the cylinderhead, there are still some sort of shims present. These shims affect the airflow.
My tuner did not know if i have to delete the shims or just let them be.
Is there someone here who did a runner flap delete or who fitted an other manifold?
The shim (or partition as it is sometimes being called) looks like this:
