Have you had your intercooler off the car yet? If you have, was there an oily film coating inside the piping and IC? If there is, you have your answer. The AOS is designed to help eliminate that problem.
For piece of mind you should check ... Then make the decision.
You will have some $$ tied up with the purchase and time/labor involved with installation... (if not DIY).
