(Our AOS will allow your engine to run more efficiently due to the separation of oil from the intake system. When there is oil in your system, the result is 1) reduced fuel octane 2) higher chance of engine knock(detonation) 3) worse emissions 4) higher oil consumption.
If you are running boost 20psi or more the blow by oil will build up on your intake, pull the intercooler and see for yourself. This AOS reduced that oil buildup greatly.
