MST Performance supplied their Mk7 GTI Cold Air Intake System for testing. As with other intake systems that I have tested for the GTI this system was first placed on the flow bench for air flow measurement.
The air filter housing has a removable cover that will be in place for this test.
The MST intake system is attached to the flow bench using an adapter that simulates the turbocharger compressor inlet.
The MST intake was tested at 28″ of H2O as have other intake systems that have been tested. The airflow measurement for the MST intake is shown on the chart along with other air intake systems that have been flow tested.
The MST intake produced the highest airflow reading of the intake systems that have been tested flowing 401 CFM, a 19% gain over the Mk7 GTI stock intake system.
