The Porsche factory AOS system is notorious for allowing for significant blow-by of oil laden vapors back into the intake system. This vapor quickly deposits a nasty film of oil inside your intake manifold, and - in the case of direct fuel injection engines - can quickly lead to crusty, grimy build-up on your intake ports and valves, reducing performance over time.

Our cleaning adapter plugs right in to the existing vacuum connection at the top of the intake manifold, just after the throttle body, allowing you to spray your preferred intake cleaning product directly into the system. The adapter comes with a rubber plug to seal the vacuum system while not spraying cleaner into the intake.

For best results:

• Use OUTSIDE in a well-ventilated area! (Exhaust fumes can be harmful/fatal when they accumulate indoors).
• Vehicle may stall when spraying cleaner. We recommend that an assistant maintain a reasonable amount of rpms to keep the engine running while cleaner is applied.
• Most cleaners are flammable!!!! Please use extreme caution when spraying so as to not get product on hot surfaces such as your exhaust.
