What does 'universal fitment' mean?

Universal fitment means this air/oil separator is not designed for a specific vehicle. You will need to determine the best mounting location and hose routing for your application. Some fabrication may be required.

How does this air/oil separator work?

This AOS collects crankcase gasses and separates the oil from the air. The oil then drains back into the engine via gravity, while the gasses are vented to the atmosphere.

Is this air/oil separator CARB compliant?

This is a universal-fitment part, so it is your responsibility to ensure it meets local emissions requirements. Check your local regulations before installing.
