This replacement filter fits the selected intake arrangement on an ETS 2004–2021 STI turbo kit. I'd use it when the old element is damaged, worn or no longer serviceable. Choose the stock-MAF 3-inch or speed-density 4-inch intake application to match the installed kit. It is a filter replacement, so it does not convert the ECU between those airflow strategies.
