In regards to the 328's it will free up airflow over stock and combined with the PE, get more performance out of the system. By itself, you will see a little better throttle response but it does not make power. If you use an open air system, you usually see losses in power in the 328. If you are on a budget, the charcoal delete plus k&n in the stock box does the same thing as the euro & PI but is a PiTA to check/change.
