What's in the Box:
As blow-by/oil builds up inside your intercooler, the less efficient it becomes due to less heat being transferred away from your engine. This leads to power loss and detonation, which can be damaging to your engine. The AOS will reduce carbon build up in the combustion chamber, intake valves, and in your intake tract. The crank case blow-by is recirculated back to the intake to be ingested by the engine, but in doing so, gets stuck in the intake tract, intake valves, and the intercooler. This builds up over time which causes a loss in power and extra wear and tear on your valve train.

The Perrin Air oil separator is a great investment. I’ve had it installed for a few weeks now and my car’s performance and efficiency has improved. An air oil separator is worth the money.
