Good but not great

Install of all AOS devices is difficult on an EJ motor. However the installation of this was made more so by hoses that are either too short or just plain cut poorly. Trying to install in the recommended hose orientation means that the hoses are too short or end up kinked.

Once installed the system works great and keeps blow-by minimal.
