Won't do anything for performance. The computer in the T/Typhoon controls the boost pressure and will not allow a pressure increase over its programmed limit. By installing the better flowing air filter you allow the turbo to work a little easier, but it won't increase boost pressure and therefore no extra power. If you are going to mod the intake system, you really need to do the lot (Air filter, Intercooler, Hoses etc) and get it tuned (psi increase) for the better airflow.
