That would be best but one problem. From the time you switch the Filters you will still need to drive around for 50-100 miles so the DME can totally adjust itself for the new airflow it feels. So switching them out may actually turn out worse. Maybe you should look into some RPI scoops and force airflow at speed through your filter
