Mk7 GTI Stock Airbox Airflow Test

Stock Airbox-Filter with MST Parts

A flow test is performed to measure airflow through a stock Mk7 GTI airbox with the snow grate removed and using a MST inlet hose and turbo inlet pipe.  This is a variation of the MST/Stock setup that was compared with aftermarket intakes.  The change in this case is the substitution of a stock air filter for the aFe filter.

The change from the aFe air filter to the stock air filter produces a drop in airflow from 383 CFM to 375 CFM.

    Thanks for the review, very
    interesting.
    In Europe is very difficult to find aFe filters, any good alternative?
