The WIX air oil separator measures 11-3/4 " by 5-1/2 " OD and is designed to efficiently separate air and oil for optimal engine performance. This separation reduces oil consumption by capturing oil particles effectively, which in turn enhances engine life by preventing oil contamination within the air intake. Additionally, it minimizes engine wear by reducing dirt and debris in the oil. The easy access design streamlines maintenance, making routine checks straightforward and less time-consuming, thereby contributing to overall engine efficiency.
